I have a question, while it works almost in every MMORPG I have ever played and in some collection RPG too.
Why isn't reflected dmg count from dmg before damage reduction, that means:
Champion skill multiplier × source of damage (deff/attk)×%damage(white dmg, crit dmg, glancing hit etc.).

Or somehow like this, after reflected damage should be percentage of number from previous formula, like 15%,30% etc.

That's would mean when champion has absorb shield on but takes no dmg + having reflection dmg buff in itself, then attacker is still hitted by damage he would deal instead of 0 dmg, because of it doesn't penetrated....
