Regarding the Life Blood Golem, I think it is going to take almost a full minute for us to take it down, and that is if everyone gets onto it. I had noticed that our attacks on Anashti were limited a lot because of the Golem and often it was because when the golem spawned we broke off attacking Anashti and took on the golem, then Anashti would cast her Holistic Health on a couple that were still near her, the golem would die, everyone would return to Anashti and nobody would be able to do any real damage to her. I know I was trying out various approaches dealing with the golem but nothing seemed to work until I noticed the golem was spawning just before everyone had to go to the aura to remove the holistic health buff.
Based on this, I would recommend the following approach. When the golem spawns, the tank grabs it and moves it into position. But nobody else goes to the golem until they have to get into the aura to clear the holistic health buff. At that time, everyone runs to the golem and takes it down. When the golem is dead, everyone runs back to Anashti and, within a few seconds, receives the holistic health buff and starts to dps Anashti.
I think later on, when we get better weapons, we can start trying other things to speed up the raid. But for now, I think this will maximize our dps on Anashti without letting the golem survive long enough for there to be 2 golems at any one time.
