If you like to ruin other peoples games you should learn to play the jungle!
The title pretty much says it all. Playing the jungle and ruining the enemy teams game is what your should be striving for. It is like a perfectly acceptable way to make someone else have a bad time and Riot will not punish you for it! The reason I say this is last night me and my brother were a Duo for about 8 games and we got jungle/top lane every game. All I did as the jungler was camp top lane for my brother which caused 3 of them to quit out due to me camping them and every other one of the typed in /all chat fuck off or something else extremely mean. I ot way to much enjoyment out of this and we won all 8 games. I also ruined 8 top laners games that day. Was such a great feeling ruining someone elses game so hard they flame at you all game or quit out. The best part of all of this is that this is 100% accepted by Riot.
I approve.
