Nasus is overpowerd
Let me show you why he is overpowerd: -Good at all stages of the game(Yes even early game when he gets sheen) -Masive dmg without dmg items -Even if he is 0/100 he can still one shot ur adc -A point and click 5 sec root with a 7 sec cooldown. -Ultimate is busted -Good gank assist -His w reduces attack speed to 0.9 or something like that -Massive healing without life steal items.
Now he has only 1 downside: he dose't do that much dmg before sheen. How to balance him: I think they shoud make his passive only 30% effective vs minions. The ultimate no longer gives him cdr on q and no more bonus hp(he still has bonus armor and aoe max hp magic dmg) When he dies he loses 50% of all stacks(so he can be punished)
