bans for talking trash are a bad idea
in my opinion banning people for trash talk is a bad mistake. ban them for scripting definitely, for trolling yes. for afk? probably if it happens too many times. but for trash talk? why?
because it pisses you off? so what? that can be a good thing!
there is trash talk in every competitive sport ever made. i have seen hideo nakamura trash talk his opponent in chess! and i believe it is good for the game.
when someone on the other team is talking, it makes the game mean more. it makes me want to beat that kid and shut him up. how can that be a bad thing? yes if a trash talker beats me then i am more upset than i would have been, but that is all part of caring about the game more.
if everyone is polite every game and just says 'good luck' and 'well played', well that is fine and i can respect those players, but the game has less value. it has no emotion. it loses its edge. i would much rather play against the trash talkers. it is the difference between a PG movie and one rated R. PG movies suck. they are too soft. no flavor.
and that is what many people want to turn LoL into. a PG rated game experience. i guess that is fine for some people. especially it is good for young kids. but if you ask me i prefer competitive games with some edge.
