I'm bad during early game, in the jungle, at playing anything but ADC or APC, leashing, Twisted Treeline, Dominion, calling MIAs, last hitting under towers, hitting with Ashe's ult from a distance, paying attention to recommended builds, map awareness, not facechecking bushes with an ADC, remembering to recall, ganking, communication, building in short games, playing aggressively, staying alive, mid against Kat, Talon, turret diving, getting kills until very late game, surrendering, and trolling.
I also tend to let people die who annoy me.
And I really can't troll. I'm terrible at it. If I'm dieing over and over and have no kills, it's because I'm just that bad.
