Riot, are you getting rid of crit during the marksman update?
I'll be frank, the stat should've been removed at the same time you removed dodge. But time moves on and that's not quite relevant. All that remains is that crit's an awful stat. It makes a ridiculous power curve for ranged AD's that hits them mid game and makes the flat ridiculous late. You'll never really get away from the fact it's a entirely luck based stat in a skill based game. And it makes AD itemization extremely wonky.
In terms of reasons why it shouldn't be removed, I believe I've only heard one. "But what about ranged AD's?"
It seems you're working on the mandatory class at the moment. So, really, there's no better time to right the mistakes of the past. So're we gettin' rid of crit now? Timing's perfect, water's warm.
(or not, I'm all for Yas nerfs)
