what this guy said.The cloak in MoP actually takes a lot more work from individuals than any other legendary in the past. Wanted glaives? Wait for them to drop! Want the healing mace from Ulduar or Shadowmourne? Leadership just picks you! Want the FL staff or DS daggers? Same thing!
With the cloak you've got tons to collect 72 items from a raid, which can easily be compared to the others because they were simply clearing the instance every week, spend 3 weeks (6 for some of us) doing nothing but farming valor, and grind a rep to exalted. That doesn't count the solo scenarios. A lot more personal accountability where in the past you just had to be the guy/gal the guild decided to give it to.
