I have noticed something about the new stat Leech, im sure you guys have aswell.
And that is that leech seems to be ignoring healing reduce effects, mind you I have only tried it in legacy raids, where leech is godawfully strong. So I cant say how it works in PVP. But it seems to me that it surely cant be intended for it to ignore it completely. Take halfus for example, he stacks his mortal strike to 96% reduced healing. No problem, second wind or juggernaut healing just laughs at it and carries on.
Another example is Cho gall. If you get your corruption to 100 you get transformed to a faceless one dealing 100% more damage have no cast times etc but you cant recieve any healing...well leech just pisses on the healing reduce and keeps going. So, is leech broken and we should expect a nerf or "intended"?
