I don't play fighters online specifically to completely stay away from lag issues, I already play FPS online and the lag is crippling sometimes. It really bothers me when someone is lagging out my Gears match and then that team just runs around charging their chainsaw.

I have a couple of cheap friends at Smash though, which is the fighter I play the most. I have one who will do his best to avoid all combat from the beginning of the match until everyone is down to 1 stock or there is only one other fighter left. It's a pretty gay way to play, but he's a legitimately good player and probably the best in the group.
