We had a 3-4 wipes at the start down to not understanding the adds and then getting overrun, this was amended in future pulls and aside from the ele pulling threat and dying during ascendance to adds, the adds were mostly under control in phase 1.
The problem seemed to be the swirl and movement. We started off following the Fatboss guide, the tanks on the left and right and the dps spread out in one section of the room, moving to another section as it fills up. This seemed to be going alright until a bad swirl came. I don't know whether to call for cds or run every time for safety.
After a raid break, we starting getting overrun by adds far too much again and then tried to amend this by stacking after the first sha pools went down on the offtank so he could pick the adds up faster. It was successful once but not the second try. I would say our main problem is the adds in phase 1 and being too scattered during swirl. In the last few tries I just gave up dpsing the boss after the free burn phase, and just went on add duty full time, (rogue) basically thinking that I would not spawn new adds whilst also cleaning up others.
The boss seems to be at 20% after hero so getting to phase 2 the first time, and spreading out to deal with the adds in phase 2 is also going fine. The problem is after we come back in after phase 2, we don't have hero and the boss hp seems to be going down so much slower because we are just dealing with adds the whole time. Between fatboss, a written guide on here and suggestions from others it's getting a little muddled and I'm not sure which movement strategy to stick to during phase 1.
