On the bright side, if it goes on too long you can buy 522 rings. Well, kind of a bright side. Sort of.
Hell, PVP gear (which is equivalent to PVE gear for the most part since 5.0.4) is down to 522 for honor and you can just run dungeons, convert in Stormwind (the room with the heirlooms) and buy two 522 rings within a day without too much effort.
