Nasus's Q is too strong

Just dont let him kill minions and you are golden

I dont think his Q is the problem its wither thats the problem, CC should be a choice not a spammable skill, the CD on wither is far too short for the massive slow that it gives, its almost borderline impossible to run away from him as all he needs is wither and gauntlet and you're a walking gold ATM

Nasus needs ganked hard and often. Your jungler should be helping to keep his farm down to minimal levels while helping you to get ahead if you are against him in lane. If you are not against him and your teammate lets him farm his Q or feeds him a bit, Nasus can indeed be hard to stop late game. If your team can keep wither off of your ranged ADC and keep Nasus out of melee range, your ADC should be able to kill him off before he starts to swing team fights.

imo to reduce the spammablity of late game Nasus and his fed Q just increase the CD time on it. make it more spammable at earlier stages but the more powerful it gets the longer it takes to hit with.This way he won't be able to 1, 2, or 3 shot people and also give him a little more counter activity. This probably wont ever happen, but it is a thought (like I said this is just my opinion).
