Health recovery was nerfed to the ground in pvp years ago to the point where its almost usless, witch is kind of sad since its one of the tree main stats. Health recovery also supossed to be one of the things you sacrifice when you are a vampire, but now even after the damage reduction nerf to vampire its still an easy pick in pvp. Also the set that made health recovery OP last time was alessian order that also was nerfed very hard at the same time if i remember corectly so its not like it would be as strong as it was. Also health recovery at least dosent cross heal other players.
