Ran this about 19 times in past two days:

Angra Mainyu: Nin/Nin/Nin/Nin/DRG/BRD/Tank/Nin(about11 more times of the ninja gloves)
Five Headed Dragon: Similar to Above but was primarily DRG/Tank drops no Healer/BRD or BLM items dropped off this

Cerberus: same as above

Cloud of Darkness Same as 5 Headed Dragon sadly..

anyone else getting similar drops with it being aimed toward Ninja/Dragoon and Tanking gear only dropping from these bosses with a maybe 1.6% drop chance for loot for the rest of the raid i know Dragoon was the "mascot" thingy for Heavensward but not everyone plays a Dragoon >_>
