Conqueror of The Umbral Plains  

I have follow the instructions in the top two posts, and have still yet to have Doomshade spawn. In the the new DZ spawned by AoC i have waited for the chanting message at zone in, run over and killed all 4 masters in 3-4 mins. Then waited 5-30 mins. I have done tried this 6 different times with fresh DZs from the AoC. Any insight into what is happening? Also i can not get the swarmlord to spawn either. I kill the caller, get the ground is rumbling emote then the waves never spawn. Anyone have the same issue? And then i have killed the two spirit's PH, the ice and fire mob in the two caves 20+ times over open world and AoC DZ and have never gotten them to spawn the raid target for the raid achievement. Anyone have any idea about that those also?
