Had some guild turnover in the past month or so, which has really set us back progression wise, so just looking at Mythic BRF now. Had a few attempts on Mythic Beastlord and just looking for tips/advice on how to get this fight done.
We've had a few sub-10% attempts now so it's getting to the frustrating point (spending 10mins to get to the same spot each time tests people patience). Our group gets to the point where Faultline dies fairly cleanly now (either no deaths or one) a majority of the time. It's once Faultline goes down that things get messy. People start dying from all sorts of things (super-heated shrapnel probably stands out more than anything else). We have been dropping the epicenters in pretty structured fashion starting at the back of the room and moving toward the front.
My view is that if we're getting to the final burn phase with everyone alive and failing from there it's probably largely due to failing the DPS check part of the fight (the final phase seems to be set up as a DPS check imo). It feels like the final phase takes an eternity even with time warp. Time wise we're probably heading toward an 11min fight. Looking at other logs the average fight length is 9:30 and the average number of player deaths on a kill is 8, which makes me think final phase deaths are going to be a given and its simply a case of burn the boss before we all die.
So question is, does this sound right? How do you manage the final phase? How many healers do you run? Do you have one tank solo tank the boss in the final phase and the other take care of the adds?
