So we downed Wind Lord fairly easy, once we got the last few details in order. Then we went Heroic Elegon and we realized that there's no way we can down more than 4 waves - even if we wanted to. We're going with 2 melee, since bringing in another ranged way less geared than both our melee, just wouldn't make sense.
What seems to be the issue, is the healing - or the dmg to the raid. We rotated people to soak the explosion from the add, and that part works fine. But during the transition from ph 2 back to ph 1, the adds we get from the pylons seems to cause some issues. Basically we're running out of CD's to use, and we can't kill the fast enough. Then the tank tanking them takes a crap ton of dmg, while the tank on the boss reaches a really high amount of stacks.
