We developed our own little strat for phase 2. Every strat we know of has the raid broken up all around the room to deal with the rapidly spawning small eye tentacles. However, we were getting overrun by large tentacles since we are very melee heavy. What we did was place the whole raid in one area, with a roaming offense group sent to dispatch the far eye stalks. Worked well ;p.
Please excuse some of my sloppy play in p2 (not keeping shouts up, etc) as I was busy directing the raid on vent and in autopilot at some parts.
