There really isn't any place to stealth or the like, the several page dissertation on revan doesn't help that much in a situation where they are forced to go to fight the lich king, and not the other way around (LoS plague is a good way to force people to come to you or die). And for all the power Id has, I have to say Arthas doesn't bring more damage than him, but he definately brings a whole lot more durability. Forcing the enemy to come to you also means Zack dies before Akuma (which isn't much i grant you that)
Beyond everything, it just comes down to the fact that most everything is relatively equal but the pre-battle loss of bayonetta put you a guy down, and i can easily see whoever isn't focus engaged just going wild, causing whatever fight ends up a 2v1 to be fatal relatively quickly. I will say if Bayonetta wasn't offed by a retargeted scum, it would have been just an overpowering scenario.
There is zero reason my team goes to them as my team has the stronger ranged magic. It also is not in any of the enemy team's personality to let the enemy come to them. Lastly, the stealth is a literal cloak. He could stealth on any terrain. ---
