Well, for me, I started off maining Makoto. Of course, Extend was my first BlazBlue game. I was introduced to it by my friend.
I'd been playing fighting games for a while before picking up BlazBlue, and I really enjoyed rushdown characters, so my friend told me to try Makoto. I liked how she played, but she just wasn't main material for me. So, instead of just staying on complete rushdown, I decided to go through some of the cast. Lambda, Rachel, Valk, Ragna and all that.. None of 'em stuck. But then, I tried Relius - and damn. I dunno what it was about him, but I LOVED playing as him. Since that first time I tried 'em, I knew I was gonna be spending most of my time on Relius. :3 And he's a pretty cool guy. Kinda mean .... yeah, but a pretty cool guy.
