I SO read that post even though I thought it was a bad idea...and it was, sorry... Make your sentences a bit more...organised

And to OP, ofcourse I have main-char problems, I main f***ing Ike, but I use him because he fits me perfectly, and next to him I always have Marth or Wario to fall back to, maybe even IC's in the future.
That's the thing, if you have trouble with mains (tourney-wise, like I have) just pick good secondaries, if you dislike your main, drop him and search the roster for someone new, it's easy.
