I need some help choosing a main. I've four characters I enjoy playing as and want to eventually learn how to use them all, however I'm having trouble deciding who to learn to play first. I can't decide between :CA:Carl,:TS:Tsubaki, :LA:Lambda, and :MU:Mu. I like playing Carl because I like playing two characters and don't mind the low health. I like Lambda's zoning play style. I find Tsubaki's combos easiest to learn. As for Mu, I like having the options to ether rush in or run and spam steins.
Any suggestions who I should learn first?
