Nasus can't stack. When ever I try to stack i just get jumped on and lose more then I gain.
Nasus cannot be a useful team member unless the enemy doesn't know how to punish Nasus for trying to stack. The choice between going in for that minion kill with siphon strike or staying back to not get punished is stupid, Because either way YOU LOSE. You either go in waste Q on opponent and get out damaged simply because this game is rock paper scissors of who does the most damage. Or you try to get last hits with Q only to lose 30% of your health or more getting only 3 bonus damage added to your Q, or you sit back and do nothing so.
So one way or another you lose the trade either in the short term and long term or just the long term. If you stay back you avoid damage but will never get any stacks. If you go to trade then you lose a chance to get a stack and still lose the trade because the enemy out DPS's you. I think they should make it so going in for that stack is always the better choice.
I feel like stacking should be more rewarding in the short term as well as the long term. What I mean is that the stacks really become noticeable after about 150 stacks. You can see small differences in damage as you stack up but 150 is a small power spike. When you reach 300 in 20 minutes then you are golden and are a reliable tank. But that is only in the long term. If there were short term rewards that allowed him to stack with less risk would mean that Nasus could be more of a help more often. Nasus should be a character where getting that bonus damage should be a risk. He relies on it to be effective so he should be able to have a way to stack safely without overwhelming amounts of punishment for it.
However stacking shouldn't be punish free. If he was guaranteed a way to stack by always healing back the damage you do to him then he will reach 400 stacks in 20 minutes and you wouldn't be able to stop him. However currently the punishment for getting stacks is far too much. So I say that maybe he needs a way to heal back more health so he can sustain him self in lane so its safer to stack.
So i suggest this:
Nasus should get a special shield when casting his Q that is worth a lot of hit points but goes away if he damages a champion with his Q or 2 seconds after successfully killing a minion with it. If you fail to kill the minion then the stack goes away immediately upon hitting it, and, If your shield is destroyed before you attack with the siphon strike buff then you lose the buff. So if he fails to gain a stack successfully then he gets punished. So this way It is more rewarding to get successful last hits with siphon strike. But if you decide to trade then you lose the shield and will take damage in addition to the enemy. So no one wins the trade because you dealt near equal damage to the other. It makes perfect sense to me. He can control trade condition just by stacking. So no trades result in a win or loss so you just keep stacking. The counter to all of this would be easy. CAMP HIS LANE. ITS THE COUNTER TO LEAGUE OF LEGENDS IT'S SELF.
If you disagree with this tell me how to get around getting punished really hard and still get stacks efficiently. THANK YOU
Would be so ballistically insane to deal with in your suggestion.
