There's something about it. I play her with a rushdown style and a lot of people don't expect that. Ever since I started playing, it felt like I keep getting better and better with her. For example, I didn't really stand a chance against Superman players, but now, I can go toe-to-toe with them. My real problem is Green Lantern. Batman was originally my main, but now Rave has easily taken his place. I guess what I'm trying to say is, I love Raven <3 I wish more people used her. The few I ran into are either really good with her or really bad. In either case, I would take/give tips from/to them afterwards.
I hope she makes the cut in the second game with a similar playstyle.

I also main Raven, and have since the game came out, although I haven't actually played in months until recently. I too find her to be a lot of fun to play, and she is definitely underused in my experience playing against others.
