Conqueror interaction with damage modifiers (MAKES YOU LOSE DAMAGE)

Sorry for the caps, i need some attention on this. Time ago i posted a post that Conqueror reduced healing from physical damage by 20%. Now i make a post that Conqueror makes you deal reduced damage.

Conqueror's conversion applies before anything else, before resistances, before damage reductions and before damage amplifications. What does this mean? Well we can make a simple example. If the enemy has 0 armor, you deal 100 dmg, you're without Conqueror but you have Last Stand's damage increase (11%) you will deal 100 * 1.11 = 111 dmg If you proced Conqueror, you will deal 100 * 0.2 + 100 * 0.8 * 1.11 = 108.8 damage. This is a 2% loss. With some other math you can find the damage amplifier formula for this interaction which is: (((enemy's armor or enemy's MR) + 44) ÷ 5)%.

The loss is not big, but there's a loss considering you're taking a keystone for damage increase. This loss continue while the enemy's armor is below 5.5. Once it gets above that you will start gaining damage. This loss becomes even bigger the more damage amplifiers there're, like PtA, Liandry, Lord Dominik and Abyssal.
