Remove crit, give ADCs a damage stat like lethality to compensate

The one thing these last two seasons have shown us is that ADCs don't actually need Crit to function. We've seen armor pen heavy builds and lethality builds and while those builds are laughable in damage compared to a full item Crit carry, it's simply better because of its early/mid game spike and the simple fact you rarely reach 6 items these days (you're lucky to get 5, let's be honest).

I don't think that's necessarily a bad thing if: we trim the early game/mid game spike down and slightly buff it late game. The reason why I wouldn't simply to this to lethality Is because lethality wasn't a stat really intended for ADCs. And I would hate to see AD casters have their various items nerfed/changed again because ADCs simply abuse them better. So why not give ADCs a similar stat that interacts with their kits and AAs more cleanly? I think now is as good a time as ever because let's be blunt, the process to getting a full Crit build is messy and typically frowned upon in most non competitive situations - not to mention, it has such polarizing scaling, I'm sure it feels like shit to play through.

I realize this would mean some direct changes on certain champions (Yasuo, Tryndamere and Gangplank come to mind). But let's be honest, most champions with built-in Crit mechanics are horrendously designed or are far too complex as is and simply don't function fairly in this game when they're even half decent (Yasuo/GP).

This would be an ambitious project. When I say now, I really mean down the road. But now is a good time to discuss this because it's clear that we are seeing examples but where Crit isn't required on ADCs and despite lethality being too strong last patch, I still much prefer a more realistic, consistent set of damage over getting hit for 200 damage one attack and 500 the next. You can make lethality consistent, you can't really do that with Crit, even if it's pseudo RNG.
