Well I think of it this way.
Umvc3. One touch and you're dead.
Spiderman infinite. One touch and you're dead.
If you get hit by the infinite you fucked up. Same thing as getting hit by zero trilogy or other teams in 3 imo.
Just don't get hit.
I didn't like UMVC3's gratuitous ToD combos either. It's no fun not being able to actually play.
