Why you doing that to us ? if you can't play champion don't play it in ranked.
http://prntscr.com/jkfdpe Like zed is hard champion and you can't play him by all means, you lose to lux in lane and you cost us a game.
And from 2 days i get a kat who couldn't win against veiger or get out of his stun box.
I don't know maybe play easy champion to climb in ranked instead of try hard one ?
maybe

Garen is straight forward you see someone coming you run while yas can't just run he need to dash around minions to get cs and yet in same time need to avoid the ganks through minions as well.
