I give up.
Obviously, the champions I enjoy just aren't fucking worth a damn, since I can't compete against braindead clickers. So, I've given up on having any semblance of fun in this game, and I'll just start playing champs that are so pathetically easy to play, yet absurdly strong, that it feels like I'm cheating. No more Lee Sin, no Gnar, no more Teemo, no more Bard, no more Kassadin, none of that. I'll just start playing Kat, LB, Pantheon, Trundle, Kha'zix, Rengar, ADCs and the like. Click people to death and win for no good reason -- but hey, I'll climb, right? Not supposed to have fun in ranked anyway.
Thanks for letting me see the error of my ways, Riot, playing a video game to try and have fun and all that. I can see now that the only way to compete is to play boring as hell champions and win without really feeling like I deserve to.
Any other boring, braindead champs that are basically guaranteed wins I should know about? I'll add them to my roster of winning without enjoyment.
