It's so not fun to play against champions that plays Conq. True dmg overall is not fun.
Only reason i like Conq is because im using this on Illaoi (main) when Im laning against tank or there are tanks/brusiers in enemy team or I know enemies will build armor. I can literally one shot tanks with combo when Im using Conq. As much as this satisfies me, I know it shouldnt be like that. Im not really talking about Illa right now but this rune.
It works same for Irelia, Rene, Darius etc.
Sugesstion - Decrease true dmg to 6-8% and revert AD changes (nerfs)on this rune. It would make Conq less opressive and buff armor users a little little bit.
