I've found that I tend to stick with the characters are fast with little power, Talim for example. I've loved her since I played 2...and she's just gotten...jumpier, but that's what's fun. She's surprising.
I also like Amy, just because I do. She's fast, does alright damage...but I LOVE her...
Hmm. My favorites to use are probably Amy, Tira, Talim, and Mina.
Least favorites to play with are Rapheal(he confuses me since I started to play with Amy), Ivy, and Lizardman.
I never really pay attention to whatever side I'm on. When I play online, I constantly switch between the two (I apparently fight against people with a preference and they normally want the 1P) But, I guess I'm alright with both of them.
"Effort, Talent, they are meaningless." -Amy (well, at least I THINK she's saying effort...not quite sure)
"Hurray! I found a new one!" -Tira
"You're so....annoying!" -Tira
"I'll make you cry!" -.....one of my characters...
