Guild loyalty and preparedness are listed amongst the reasons why the Hunters were passed up for the legendary drop. Phase, from Vicarious defended the decision to hand Thori'dal to a Rogue:

Though I can't speak for Kharhaz on this matter I can see why he would want to give Analogkid priority on this over Tums and Zzerg. Analogkid has been raiding with us since we rerolled here and were doing kara and gruuls lair. He has had an excellent attendance and has given his best using full consumables alot of the time, even on farm content throughout all of raiding from t4 to sunwell and in this respect deserves loot, especially legendaries over people who transfered to our guild after we killed pre-nerf M'uru, a fight which i might add that was very trying for our guild.

Analogkid already totes both Warglaives of Azzinoth, weapons that are not available to the Hunter class. The OP, Rentaaki, reported that both of the Hunters that were passed up for the weapon found the affront to their loyalty to be disrespectful. Raid leaders do have discretion to distribute loot as they see fit. I'd like to believe that the guild has a system in place that justifies the distribution of loot. If the guild continues raiding, they may see Thori'dal drop again. It seems to me that the chances of getting another of these beauties to drop would be increased by giving it to Hunters first and then Rogues and Warriors. It's not my guild, and they can run it any way they want. For now, I think I'm going to be sick.
