T2 Enrage problem

[Ri_ri]

we're all pretty new to coil in my FC and just did T2 first time the weekend and wiped in enrage mode. don't exactly know why.
me as a brd had ballad up, 3 healers, one tank, 4 dps, and still we wiped because healers who spammed all those aoe cures ran out of mana.
what went wrong?

Give it some time before using the next AoE to minimize over healing.
