conqueror doesn't need 8% true damage. It needs 10% armor pen.

I would rather the true dmg be taken away and the ad gained increased

Conqueror is already a bad rune, make that change and noone will use it ever. I mean, why would you waste our main rune for 10% armor pen which is completely useless in early&mid game and teamfights? Bruisers want to kill adc-s and mages in late game who have barely any armor anyway. I'd rather take electrocute for great early and mid game damage then buy LDR with 35% armor pen if it is worth the investment.

Conqueror doesn't need any more nerfs. It's fine
