The reason why Im a good Sweet Tooth player is because I utilize all of his attacks. Some moves arent ment for offense, but for defensive purposes. People dont have any meta game figured out right now. give it time.
and most fighting games boil down to only a few moves. Look at UMvC3. Like 90% of the players use about 4 Wesker attacks, 4 Doom attacks, and maybe 1-2 Zero and Dante combos. Some moves are just pointless to use.
