Darius passive needs a half rework

I love playing Darius, but in its current state, his passive makes him extremely unhealthy for the game and hard to balance, due to him being either too strong or completely useless. My proposal is this:

Passive: Noxian Might no longer gives ad at max stacks. Darius’ abilities have their effects enhanced. (Keep in mind that the bleed effect is still there) Damage at full stacks now scales with 170% ad from 150

The following numbers are just me spitballing

Q: Now heals for 2-4% more per target hit. Everybody has healing debuffs anyways

W: Now does 20-100% of its damage as true damage similarly to Camille’s q, making him stronger against tanks without bringing his damage towards squishies up that much.

E: Increase the cooldown to 30 at all ranks. Cooldown is reduced by 1.5 seconds whenever you land a basic attack or the end of your q. Helps him to close the gap between him and say mages or adcs.

R:Unchanged
