I'd probably be for turning Rage off if that's the case.
I'm curious on Smash meter too but quite apprehensive. I also would rather more stocks if the game is fast enough. But I fully understand the concerns of TO's when game times get long.
From what I can tell, the damage has been upped in this game, so I imagine the speed will go along with that. I think 3 stock makes it more probable that the more consistent/better player wins.
