So this is a knows matter but i just want to bring it up.
I recently tried a Targo Warlord build that happened to have about +500% trauma duration. When i hit some reflection mob (inevitably i do in crowded fights) check this out : With no reflected damage reduction, i take 7400 damage for 30 seconds. You heard it right, over 200k damage for single hit.
I stacked 94% Reflected Damage reduction (thanks to updated Titan Plating on helm and chest) and its still 439 damage for 30 seconds. I mean how often can you stack this much reflect reduction honestly?
The reason for this kind of damage is, because most builds usually dont go more than 30% or so physical res while your other resists are capped. So physical reflected damage is obscene compared to other elements.
I really belive this is an issue and should be adressed.
