You ever play with a community/clan? They're a great way to meet some new League buddies to play with. I'll go ahead and plug my own http://feverclan.com/forums/forum.html
I'll admit our forum posts are a bit inconsistent, but the TS is pretty busy. We don't have too many high ELOs, really just myself(D5), a Master tier couple, and quite a few plats. I spend most of my free time on there so feel free to come and say hi if you do join. If you don't want to join, no worries. Shoot me a friend request/game invite anytime either way. Best of luck finding buds :)
