Characters in fighting games aren't balanced most of the time. Regardless of exploiting glitches to perform certain techniques, some always end up doing better overall than others and in some cases also outclass them in most areas, which of course leads to X character hardly being used. It is indeed hard to have balance in such games.
Getting patches through online would be cool, heck maybe even more items for the stage builder, new stages and more characters, but I really doubt Nintendo will ever do this...
Right now, I don't really know who I'll main. I wasn't so good in Melee to begin with and never got competitive back then. I'll need to get a feel for the characters in Brawl first. Some I'm really looking foward to try out though would be Lucario, Sonic, DDD, PT, Meta Knight and the new and improved Bowser.
Not sure which controler I'll be using either, but I'm definately trying the Wiimote + Nunchuk.
