Its not like you have to use a timer all the time even when playing lvl 9s. Its just at tournaments, and just so you know, at tournaments its not the same as you and your buddies just smashing. Theres friendlies and people do that before, after, and even during the tournament. But a tournament match is played very seriously...except against me because I always yell out 69 variations. M2K was getting mad at me for calling them out and talking during our sets.
A small tournament could forgo the use of a timer just like it may forgo the Hyrule ban, even players could gentlemans a non timed game if they both know they're not going to be ***** and try to camp. But having the ruleset allows for the game to be organized better and smoother than it currently is, in my opinion.
I'm not saying ban characters, or ban stages, or ban items, or ban stocks, or ban coins, or ban moves, or ban handicaps, or ban costumes, or ban keyboards (I take that back, ban keyboards), I'm just saying that for competitive and very serious matches, we should have a ruleset that prevents players from stalling matches and camping indefinitely by virtue of a timer.
