While you're blazing your way through the Sunwell Plateau, don't forget about the other items you can nab along the way. In addition to the gear and items that drop in the raid, bosses drop Sunmotes, which can be traded along with various loot drops in Sunwell Plateau for other loot items. To trade these items, look for the NPC Yrma aboard the boat in Sunwell Harbor.
In addition, there is also plenty of unique-looking gear on Smith Hauthaa over in the armory section of the Isle. Unlike the other gear to be found on the Isle, everything that Hauthaa has can be purchased for justice points rather than fished out of an instance. If you've got a glut of justice points, it may be worth it to check out Hauthaa's wares and see if there's anything that catches your eye for transmogrification.
