I don't think that rubbish stats for socket bonuses is gamebreaking at all, but still i'd like to know why spirit makes its way onto our PvP gear. At best, a red socket in the helm might provide 1-2sp from the spirit, at worst it gets you a trickle of sliver outside the 5 second rule.
Did they just copy the tree bonuses? Or is it a leftover from a time where Blizzard wanted Moonkins to want spirit?
