While i would love my 45ms ADSL2+ ping to be 45ms instead of 180+; i think whats more important is getting teamed up with people that UNDERSTAND you and you can UNDERSTAND them. just as the timer has completed and you get "hablo espanial que?" there is a 9/10 chance that this Spanish/Brazilian/Portuguese person is going to come along and last hit your red, blue, ks, feed...
What i would like to see is a greater language filter. Riot emphasize on teamwork and communication... How can you do this when 1 person does not understand the rest of the team, or 2 of your teammates spam chat about useless banter that is totally non-game related?
