Why do you need master loot if you are running with guild members? Set it to Need/Greed. Establish loot rules. Need for gear you are going to use for your character, Greed for companions. If you don't need a thing, then pass on the damn gear. It's not rocket science....get your head out of your asses and learn this isn't WoW. If you are pugging operations, then you must be doing it with friends...because most people aren't even lvl 50 yet on most servers. Most servers have 6 or less lvl 50's on them...Are you people really that stupid and naive?
what are you even talking about? Normal mode operations auto-assign loot.
