EC: Warlord Kephess (Story Mode)

[Qed]

On our kill this week, we seemed to be taking absurd tank damage once we got to the 'gift of the masters' phase. The bottom of our log looked like this:

29K damage in 1.5 seconds was, I believe the term used was "impossible to heal through". We ended up having the tanks kite in this phase which seemed to keep them alive, but I'm curious if other people are seeing this kind of burst (and if so, how they handle it).
