"oh, save cds for 35%"
yeah, try killing a warrior with 25% DR at all times, behind shield wall, while your cds are going.
then you have no cds and still have to deal with 25% DR.
of all the things blizzard could hotfix, why not second wind? its a % based heal which isnt affected by battle fatigue (unlike say, ret/feral/enhance heals)
if anything is a cancer in pvp, be it arena or rbgs, its this stupid ability.
