You're the most aggressive wario I've ever seen. You know what happens to aggressive Warios? They get grabbed. And we all know what happens after that. Its mostly why I quit the character (and largely Brawl in general). I actually enjoy fighting in fighting games. With wario, you're either camping or in a chain grab or grab release.
Then again, the only snake I've met more aggro than yours is ct's, but that style works for you, so whatever.
I'm probably going to go back to snake as my secondary, because I like having control of the stage and not perpetually existing in an air or spot dodge (living in my shield is more fun). Has a favorable matchup on marth too, which is a plus.
Edit: I will probably quit Kirby once I become proficient with MK. It is confusing to play the character between both games. Hell, its confusing enough to relearn what's possible every time B+ changes. Since I've never had more difficulty learning a character than I have with him, that will probably take a while.
