Lichking valkyr & defile

[Aequi]

Does anyone know if there is an addon, that can help with the specific situation of Valkyrs and defile almost at the same time, during Lichking encounter. Already use DBM.

Basicly one known strategy is to stay very close together to control valkyr's direction, but since Defile is an AOE damage effect that preferably should only hit the one randomly targetted, we need to quickly spread out before the defile.

Been looking for an addon that can tell me that valkyr(s) have selected their target(s), something that can help me identifie, either with sound or flashing that a target has been chosen, and its time to spread out - and avoid defile.

Anyone know such an addon??
