I was never the type to play well with the entire cast in a fighting game. In every street fighter game I played Guile unless he wasn't in that specific title, and in MK games I play Sub-Zero. In Injustice I feel like I'm pretty good with Batman. I tried messing around with other characters, but Batman is my hero lol. I'm more of a character loyalist. Like other people pointed out... It's nothing wrong having one main, but it does force to KNOW your match ups. Some people can be GOOD with a lot of characters, I'm not that guy though. I just learn my one character & work on the ins and outs of them.
