Keep Hexakill.
Idk about you guys, but Hexakill is probably some of the most fun I've had on this game.
I can crunch in a match within 20 minutes, instead of the usual 40+ minute SR games.
I was fucking trash and not even level 30 when I tried URF, so I don't have much to say on that.
But Hexakill is awwwwesommmmeeeeeeeeeeeeeeee
Which gives me time to league before work.
