Let's let tanks, tank, a little. Please. 1 simple change...
passive changed to Conqueror. Same name, and shares the same name, NOT EFFECT, with the rune Conqueror.
This way, you dont deal 40%+ true damage, cause that's not fun..... Please.
I'd honesty want conqueror to be half as effective on certain champions who already deal large amounts of true damage... 
but there's no way riot will let that happen.
