As a Full time reaver this is what i got.
First of all, I dont want any of the reaver healing skills to be nerfed unless guardian/warden healing skills will get a nerf.
Increase the DPS of the reaver overall, and not only impale. Because at Raids, we are pretty not doing anythinng, our DPS Does nothing.
in 1v1 its pretty fair, even without impale or any healing skills
