there's a difference between loving it and it being practical to get noticeably better. look, if you still have the drive, awesome, great for you, but you have to understand that for some players, the prospect of having to drive 30+ minutes each way on a weeknight after going to work and the gym and preparing dinner and cleaning up just isn't appealing anymore. I love Melee and wish it were easier to play, but it's just too inconvenient at this point.
EDIT: and oh yea, all day tournament are so tiring. I dunno how I used to be able to do it in retrospect, but nowadays I just don't wanna spend an entire day playing Smash.
