Unpopular opinion about Graves E, I think it's fine

It has to be stacked up 4 times to get the full potential and while I know that is easy late game when he has health and sustain but if it's really that big an issue here's my idea on how to change it so he isnt at near 300 armor and mr late game.

Change the E to go to full stacks on use but the duration can't be refreshed, you need to attack enemys to lower the cooldown to use it again. Prob lower the base cooldown a little.

How it is a nerf: prevents him having a ton of resistances late game even when he eventually goes oom. Nerfs jungle clear health for those who don't kite. Also gives people a more recognizable time to back off before blowing him up.

How it is a buff: can now survive bursts when before if he didnt stack it he couldnt. Increases his early/mid game dueling potential for the first 4 seconds. Gives him a meaningful choice of "do i need to get tanky now or should i save it for when the enemy retaliates?"

I think it's fine but this is an idea if you want it nerfed for his obnoxious teamfights late game where he becomes a ranged juggernaut.
