The best remedy to online balance issues is to play in offline tournaments. ;)
What do we know about the specifics of how meter is built? Is whiffing a move enough, or does it require your opponent to block an attack? If the latter, I think there's potential for a significant meter advantage not for long range characters, but for string characters like Maxi, Natsu, etc.
I assume (probably a big mistake) they will be smart enough to balance it on a move-by move basis, a la Soul Gauge damage in sc4.
