Nasus' Q should get decreased CD on successful last hit

As a 1 million mastery player with high elo experience (peaked diamond), I think that 's split pushing is too slow, especially comparing it to the likes of , , etc. Not only that, but in order to increase his waveclear he can only cast E that doesn't even kill ranged creeps on its own so has to auto at least once more. This only makes it harder to last hit and it is counter productive towards his stacking game (Q max), which is the only relevant scaling he has. That being said, it'd be nice if his Q got reset once it kills an enemy unit, especially since his trading is the worst in the game i.e. once he walks up and stacks a minion with Q, he has no trading tools, which is usually the 'go to' signal for the enemy laner.

If this in some way becomes too powerful, it should at least get its CD cut in half (as if he has ulti on). And if this version gets implemented, the %CD decrease should maybe stack with ulti, so that his stacking speed increases in mid-late game if he decides to use ulti to threaten enemy structures. Thoughts and opinions?
