I can't stand ADC's
But nerfing Cloak was not the answer. The truly cancer adc's that needed nerfed will still be ever picked because they are the best;

I do appreciate the targeted nerf on Caitlyn, but over all nerfing adc itemization was the wrong move.
It's just like the jungle. You went in with the stated goal of reducing gank heavy junglers and only ended up solidifying their stance as the best jungler type.
When will Riot see that targeted, individual nerfs are best and that nerfing an entire class through items only serves to maintain the status quo for the champions that already were too strong?
