How's the balance in Tatsunoko vs. Capcom?

I've been keeping an eye on the game and it looks really fun. However, as a Smash veteran I can't help but worry about the balance. After what happened with Brawl being unbalanced as hell (and fixing it through Brawl Plus), I don't want to buy another fighting game unless it's fairly well balanced. How does Tatsunoko vs Capcom fare as far as balance goes? Are there any characters or tactics that do so well that they make certain characters unplayable, or akin to suicide? Is the gameplay well-balanced between offense and defense, too?

its a pretty good fighter i happen to have it and haven't seen anything that's unbalanced
sure there are lots of character pairs that it can seem like there unbeatable and even some with infinity combos but overall its balanced
just learn a good team and practice
im talking about the online gameplay not offline
offline is pretty balanced

ugh.. i hate that game.
