Give nasus the veigar treatment?
Nasus is pretty broken right now, and it could arguably be because of klepto coin, but I think he can use some power readjustment regardless of the fate of klepto and coin.
Tie his Q cooldown to number of stacks he has?
Perhaps something like -10% base Q cooldown for every 75 stacks?
He doesnt get to auto win level 6 anymore, his lategame infinite scale fantasy gets a bone toss, and E max nasus which is an inherently toxic ass playstyle gets nerfed, 3 birds with one stone.
