My guild and I are doing Kephess on hardmode and have been experiencing issues with how to survive Kephess' empowerment (Gift of the Masters) after today's patch (24/04/2012).
When he reaches 65%, he is empowered and the raid is pulled into the middle of his purple aoe.
Our response to this was to immediately leave the purple circle but even when we have left the circle we all drop dead after taking approx 20-30K Damage each.
What have me missed? :
