And actually, genuinely, what is the difference between bloodlusted and SBA if this goes through, the hero doesn't care about EITHER the bystanders, OR the opponent surviving, why WOULDN'T he go max strength? Aside from a few rare examples where characters are just "playful" I don't see any other reason.
Why wouldn't Superman and Hulk just blow up the planet as the opening move? They have LITERALLY nothing to lose by standards imposed.
We made SBA "Uneven Bloodlust", amazing development. At that point it's MORE unfair to the select characters who have a fraction of their character left, like Frieza or someone, as they're now fighting an uncaring broken killing machine with no reason left to let them live
Until now bystanders were never factors in debates. Did you have the impression that our characters currently are all bloodlusted? I don't.
I generally don't think having morals AND characters present is realistic. In practice I am almost certain that it will result in one of three things in every match:
1. It isn't relevant for the matchup.
2. It is technically relevant, but gets ignored.
3. It would be relevant, so the location is changed because it would be a disadvantage to one of the characters.
Outside of some gimmicky matches, I can't imagine that anyone actually wants a hostage situation inside their duel. The cases where that is relevant and desirable are in the minority IMO and can be better managed by changing the assumptions for the threads where it is supposed to happen.
Is it the same as bloodlusted? No, it's not. Bloodlusted means the character wants to kill the opponent at any price and as hard and brutally as possible. A bloodlusted character will in most cases instantly launch the most powerful attack in their arsenal at the opponent. None of this applies to our SBA.
Our SBA conserves the character's fighting style and morals towards the opponent exist to a degree, just that they are willing to end the match by killing if they can't finish it otherwise.
Would Superman and Hulk just instantly bust the planet? Don't think so. It's still planet Earth. Their home planet and the home planet of humanity. The lack of relevant bystanders at the moment doesn't diminish that. Maybe they would if they find that they can't win otherwise, but personally, I'm ok with that.
Sure, I bet there are also other characters that wouldn't use any AoE techniques with bystanders around usually, but again, that's a trade-off I'm ok with. Our matches are supposed to be in-character, but they also are supposed to be a serious fight between two characters fighting at their best. A fight where a City level character needs to fight at Building level power to not hurt bystanders just doesn't reflect the character fighting properly.
That's my stance at least.
We could also try to make some compromise. Maybe some rule of large numbers. Like, individual bystanders are irrelevant, so that characters can fight properly, but when it comes to attacks that would wipe out the populations of large cities morals regarding the population in general apply or something. Don't know if that's a solution anyone likes
