It's now called "Group Loot" - it's an improved version of the old Need/Greed system that automatically prioritizes "mainspec" rolls over "offspec."
Round Robin and the old "Group Loot" option were removed in 7.0.3, since they were almost entirely unused. Loot options are now: Group Loot, Master Loot (if in a guild party), Personal Loot, and Free For All.
