Viola-My new main, been playing her from day 1 and knew i wanted to make her work when she was revealed. I seem to be drawn to these types of psychics and magic users. I play Kenshi in MK, Elizabeth in Persona, Phoenix in mvc3 (It help that they tend to be really good, psychics are just naturally BS). I know she's considered to be broken, and it's partially this reason i abstain from using her online. The second reason being i dont want to get used to beating online scrubs and prefer to save her for people i know are good.
Raphael- My main since SC2, until i began to get fed up with all the changes they made to him. Removed his parries, removed his super tech crouch, removed his JF foot stomp, etc. I still use him though as an alt, in fact he gets a more play than Viola when i go online. I think once i get that 2K pressure down he will be better, but he seems to be able to handle most people.
ZWEI- My second most used alt behind Raph, and i'm starting to get more comfortable using him against better players. Until i decided to use him, Raph handled everything. And suprisngly i'm starting to feel like i can make him work against everyone. That is until i run into someone who punishes and dodges everything he does, and i get reminded of how depressingly bad his grab range is.
Tira- I began player her after the patch, maybe not the best time to pick her up since she was apparently even better before. Her weapon style is what drew me to her and why i began playing her way back in SC3 and again in SC4. I've still yet to run into a dangerous Tira, but i have a feeling it would be maddening. I know i have much to learn still before i'm completely confident in her.
As for who i hate fighting against i hate fighting my number 1 has to be Mitsu, it irks me to no end watching his 4B follow me around like a surveillance camera or having his verticals hit even though i'm 5 feet off to the side. The rest i just dont like fighting Viola's bad match ups like Nightmare or Cervy.
