Whoever came up with the auto assign loot system has obviously never played an MMO. It often gives people the wrong gear, and there is literally no point to master loot. Guilds cannot use any sort of reward loot system, and you might have to see a piece of loot you need given to the wrong spec. UI is among the easiest things to code, and they completely failed at it. I love every other aspect of this game, but seriously give us a modifiable UI, control of loot, addons, and a combat text window.
