Most of the Mercenaries are comically stupid so they'd probably struggle to find Cap regardless with his stealth mastery.
You're downplaying the mercs like...mega hard here. All 9 of them are considered the most dangerous mercenaries in the world. They're the best the administrator has to offer. Every other one of her teams got taken down by the TF:Classic guys, and they were all also very skilled warriors. The Administrator doesn't just hire dumbasses; she hired them for a good reason. They are still good fighters with years of experience, some even before joining the Gravel Wars. This is just like, incredibly gross downplay. They're weird and whacky, yes, but the only one I'd call comically stupid is Soldier, while the rest are fairly intelligent or at least capable, with Scout the only other one being iffy about.
Unlocks aren't listed as standard equipment,
I will state again...
If their unlocks can't be used then they cannot hit Cap because only their unlocks are actually 8-C. I don't want to have to repeat it again. They need the unlocks, otherwise this is a stomp. They literally can't hurt Cap then.
Scout's only useful unlock here is Bonk, everything else is useless here because of how badly outskilled Scout is.
Don't need to be terribly skilled to know to shoot the guy with the guns you have. Bonk is good as a distraction to help his team out in making sure they can hit Cap. His Capper and Batsaber can also hit him.
Scout never stacks drinks either, if he can it's OOC. Cap can likely outlast Bonk anyways by just blocking his shots due to skill and enhanced senses
Never said he would stack drinks, just saying that both drinks are useful. Cap can block his shots, sure, but Scout's entire team are likely to follow behind him (there's literally one guy in 2Fort they're not stupid enough to just do their own thing), and he'd have to worry about like the 7 or 8 other people shooting at him.
Soldier's banners are useful if he can deal enough damage but that's assuming Cap doesn't just shield toss him instantly, and the Come back stronger pills we've literally never seen in action or if it's even combat applicable.
We still know that he
will come back stronger. We've seen ressurection in the TF2 comics. We see it works pretty quickly. Merasmus is a wizard and odds are he can handle the same amount of instant ressurection. And we see Merasumus like, die in the Scream Fortress game mode, pretty sure. He just comes back in like, a couple of minutes. They're Merasmus' pills, so they likely function similarly to his own respawning method.
but that's assuming Cap doesn't just shield toss him instantly
Cap wouldn't know to do that to him. He can only toss his shield so many times and if he tosses it at one person he leaves himself vulnerable to, again, like 7-8 other people who will just shoot and debuff him. This is just like, a certainty, especially since Soldier would likely be more willing to stick around his teammates (again, Blu is less chaotic than their RED counterparts as depicted in cinematics, but still somewhat out there).
Pyro flares are good here but they just get blocked probably
Pretty sure splash damage would still get him. Pyro can shoot at his feet and light him on fire that way. Cap literally, physically cannot block his entire body. He has to pick and choose.
Airblast isn't disarming Cap
Never said it would. Said it would knock his shield out of his planned trajectory, potentially leaving him completely unarmed. It wouldn't be a stretch to say that yes, the shield would be moved out of the way of its intended path. Airblasts move heavier things all the time, like a Heavy or a Soldier. The shield could at most weigh like 12 pounds? 50 if we use logic but this is comics/movies. It could easily be knocked off course. Since speed is equalized Pyro would have enough time to react to such things.
Demo's obviously gonna play his role as a defense class here
I mean have you seen Demoknights-
Cap also isn't stupid enough to just blindly follow Demo around a corner when he has explosives, he could also just chuck his shield while he's running and oneshot.
Okay, then neither of them kill one another lol. Cap can't just through his shield unless he does some weird ricochet tactics, and even then 2Fort in the close quarters areas has a lot of turns and 90 degree angles. On top of that, would he bother throwing his shield at a dude who is
currently running away when he has other people that are currently shooting at him? I don't think so. Demo is mainly the distraction here, but he can still trip up Steve by just shooting grenades at him.
The mercenaries will never be in a position that allows them all to jump Cap after the initial bridge fight
I don't think this will go past an initial bridge fight, if we want to go down that route. All it takes is one headshot from a sniper to do Cap in. Sniper is a
really good shot, and also not stupid like you're trying to make him out to be. If Cap is occupied fighting, again, like 7 or 8 other people, he will have a
really hard time dodging a sniper shot that is also coming directly for his head. Sniper could hit the writhing and rampaging tentacles of the bread monsters, which move erratically and without any real pattern to them. He can hit Cap's head if he wants, and Cap would have no time to really block it.
guy to revive them after a while.
He doesn't have any revives btw. That's a MVM thing and we're not considering that. Medic can revive
himself though by making deals with Satan with his certain amount of souls that he has, giving himi quite a few tries, and I think it's something that Steve would expect and would be a good edge during the fight. Medic is super important because his uber would make others invulnerable to attacks on Cap's level. That allows someone to just go in and wallop on Cap, or distract him even further for a well aimed Sniper shot.
Engineer's sentries don't try and use splash damage
They're missiles, they do splash damage. At the very least there's potential to push Cap back. The Wrangler can be drawn out before he sees Cap if he worries about the start up time. Engineer is like, the smartest dude on the team. He'd know what to do here.
Oh and I forgot to mention that Engineer's Short Circuit has an attack which removes enemy projectiles. Idk how that interacts with Cap's shield but that is food for thought. This is one of his vaporization weapons too so he could use it.
Sniper won't be chasing Cap down
Never said he would but I do think he could throw Jarate on him. he can throw that damn jar pretty far. He can just throw it on the initial bridge fight, if we wanna be hoenst here. It has a big AoE. If he wants to support his teammates (which he might after seeing Cap gib some unlucky Merc), then he could just pull out the Sydney Sleeper right afterwards. Or, again, the Shooting Star just one taps on Steve's head. He ain't regenerating from that. The bridge is like one of the best sightlines for Sniper. There's no reason he wouldn't be there and make it impossible for Steve to leave one side of the map in the conventional way, forcing him down a really weird path through the sewers.
Never said he wasn't dude lol.
cover more ground (which they will in character, like with the yeti)
The Yeti was at Mercenary Park, which is a really
big place that they didn't know about. It was a new map. This is 2Fort for god's sake, a map where they've been fighting for
years. they don't need to cover more ground. In the comics the team has always stuck together a lot more, because they're depicted as more rational there. BLU is a more rational version of RED team, so that's what they'd likely be doing here as well.
The teams main wincon here is just Cap ending up in a fight with the majority of them at once with team support from Medic which isn't very likely due to how Cap would likely approach the situation (stealthily and cautiously)
Medic/team pushes are common in TF2 so I can see the whole team just rushing him with the help of Medic. It's not out of the question. Cap can take this as steathily as he wants. It doesn't matter when the first attack he makes will alert literally the entire team of mercs to his location. After that, there's literally no way he can hide. 2Fort is not a map where you can hide. It's
very open. These guys have been fighting in 2Fort for years. They know this place like the back of their hand. Cap may have photographic memory but the mercs would be just as familiar with the location. It's ridiculous to say otherwise. And again, barely anywhere to sneak around on 2Fort of all places. Cap is skilled, but he really just can't take on 9 people at once when a few shots from any of them would severely wound him.
(also OP you forgot to count TheGatememer's vote. We're 1-5-0)
