And umm you guys are ridiculous with the whole wanting wavedashing and L-cancelling in brawl. No tripping is fine enough because it takes out an annoyance. It doesn't add any extra depth nor does it take away much. Messing with the game too much is just stupid. That's like saying we should add parrying to the game like in 3rd strike or Cancelling for "better combos"
Leave the dam game alone. (talking to you ELI!!) If you wanna wavedash and L-cancel. Play Melee! There's a reason they're two "DIFFERENT" games
