Alright well for starters, how's about you drop the passive aggressiveness? It's really not needed and honestly just makes you seem needlessly aggressive, I'd also suggest you drop your accusations of me "forcing" an upgrade.
1: And why would Fujitora call a typical flying slash attack whenever so many One Piece Swordsmen can do such a thing? Quite literally every notable swordsman can launch ranged attack. That argument makes no sense and is totally asinine to believe Fujitora would be impressed by such a thing. Not to mention Occam's Razor would suggest Fujitora meant the power behind the slash, not the attack itself. Flying sword strikes are nothing new in One Piece, there's no reason to assume that Issho is taking about the move itself. Also what are you talking about? The shudder is literally on the same panel with Fujitora, after the ground was slahed and Fuji blocked it, it seems to me you're the one who's trying to force your opinion despite it being objectively wrong.
2: Yes, I'm aware and I'm also fully aware that they can only cause minimal amounts of damage to Admirals. Also i don't recall Vista ever clashing with Akainu let alone being noted as a threat to him. Unless you mean whenever Marco and Vista attacked him, which isn't benefiting your argument given they did literally no damage to Akainu. Marco kept up Kizaru and co via his regen, he kicked Kizaru but did no damage, hell Marco himself Kizaru is lying.
- First of all, none of the YC inflicted heavy damage to any of The Admiral's, only superficial damage. You know the same thing that Fuji did to Zoro? You've been grealty over exaggerating the amount of damage Issho did to Zoro, all that happened was that Zoro got pinned and drew a small amount of blood. ( Due to being pinned to the ground via gravity.) Zoro then overpowered said attack, launched an attack and jumped back up ready to fight. I just find it odd how you haven't addressed any of these points.
3: Mate, while being pinned down Zoro obviously isn't gonna be able to attack the same way he usually would, that kinda happens whenever you launch an attack upwards while being pinned down by a torrent of gravity coming from above you. It'd be incredibly difficult to even raise your hand while pinned by gravity let alone launching an attack. Again, I'm not saying Zoro is equal to Issho but given the fact that he overpowered his gravity, jumped back up from the attack with minimal injuries and even received a compliment from Fujitora himself should be enough to say that they'd be somewhat comparable.
Now I'm gonna wait for a response from you either filled with sarcasm, condescension followed by several strawman fallacies.
