What is the enhancement in mind? How should it look and feel?

An additional timer providing a countdown to Chimaeron's next melee swing, perhaps by default only enabled for healers & tanks or even disabled by default. This would be especially helpful on heroic, where he continues to melee and double attack during feud, so tank healers can predict the next hit and use cooldowns or know to pre-cast a big heal to land after the melee swing.

Please provide any additional information below.

Chimaeron melees at 5 second intervals, and his swing timer is only reset by a massacre cast.
