Put your best geared tank as primary OT, your second best geared tank as secondary OT, and your third tank as MT. What I mean by this, is put who has the most avoidance as your first OT. I was running last night with about 30% dodge, 19% parry for this and I still had to alternate CD's. SB -> Moroes -> Valor Medal -> SB. Keep those up as much as possible. Last stand at your discresion, and at 7ish % use SW.
For next reset I will use the Last Stand Glyph to try it out. 2 Last stands during this fight I believe would be awsome. One at the begining and one at the end.
Also, 2 healers should be sufficient on the MT, 3 on the first OT, and 2 on the second OT. This is assuming you have 7 in the raid.
