They've changed the game significantly from beta to beta.
@karaokelove you're playing Laura: ironically the one character in the roster NOT really meant to link moderate length combos, and has a gameplay style that is misleading at first. Though even with that, a lot of characters have lost comboability.
Not sure how I feel as I haven't played much, but I've been having a blast and mopping fools. But then again, this isn't my first Street Fighter rodeo. All in all, the betas have been interesting to say the least. It's amazing how slight tweaks can make characters feel completely different.
