The rationale behind a lot of these buffs is that Graves is becoming far riskier: he's gonna need 100 armor and MR at level 18 because he'd be fighting at Urgot-level ranges and would have to stay close to his enemies due to his lack of sustained DPS. Considering he's already short-ranged and burst-heavy, I think that would be in line with his current playstyle.

Perhaps I should change the description for Smoke Screen, but the idea is that if you're inside it, you a) cannot see through the smoke, because you're inside it, and b) you lose allied vision, so your whole vision range is constrained to the smoke screen. If you're outside it, you still keep your allied vision, but the smoke itself acts like brush and obscures vision of anything past it.
