Just an FYI, I don’t know if you’ve looked at the new vendor, every piece of loot has three different versions with different stat configurations. It isn’t impossible that all three configurations are “sub-optimal” but it is a big step in the right direction short of just letting you craft exactly the stats you want.
But WoW is an RPG so honestly it is really a problem if you can get a minor benefit from getting a better itemized item from another piece of content, as long as your PvP gear loot is like 99.X% good enough?
