That doesn't look at all like the values I would expect, I would expect to see your Aim and End much closer to the 1900ish mark, and ~2k Expertise. Investigating what is going on, this *may* be a different symptom of our well known bolster bug, or it might be something else entirely.
He would see around 2k expertise from level 33 gear with no expertise on it? Surely at 55 this bolster would not be like this or else PvE Raid gear as it is in 2.0 with its significantly higher stats will out due PvP gear since it will be bolstered to almost the same amount of expertise.
If that's the case prepare to lose a lot of PvPers, Endgame PvE gear should not be on par with PvP gear in "PvP" especially now that stat wise our PvP gear is useless in endgame PVE or close to useless.
