I thnk everyone agrees that the multi-hit strikers are much better.

But leave sentinel the way he is, i have a feeling we will be needing him down the line when bigger fighters: Sabretooth, Magneto, CapAm, etc. Become playable.
And i think venom is the only one needing a revamp. I think he might be better if he does his venom-fang attack. (the one where he jumps across the screen and all you see is his eyes and teeth. he kinda looks like a shark, or a big big off goo. =) )

But anyway, the Strikers 0wn.
