Why do a lot of players hate Twisted Treeline?
are they right when they say that is more difficult to win a 3x match then a x5 (SR)?

3v3 and 5v5 and dominion are all exactly as challenging as the opponents you play against.

People don't play TT, because they get served when they take their noob skill to the twisted treeline.

cause there's huge balance issues that need to be addressed. queue times are really bad too.

Yeah, 30 minute ranked queue times can get frustrating. We need moar 3's competition! But that won't happen until some balance issues are addressed and 3's garners more competitive attention. But that won't happen soon, because why disturb the SR cash cow business model if you're Riot? :/ Business gon' business.

problem with 3v3s for me is that not every champion is viable on it. Which irks me.

Though I don't have a particular problem with TT itself. I enjoy different maps.

i posted a thread on the champion feedback & when i uploaded the pics for the match results

all the people raged at me & called me noob for playing tt
