It's not my invention, saw it with a group running a couple of days ago and from healer perspective it's much much easier IMO.

Titan-Egi tanks the King and the both tanks one tank add each. Keep king a bit away. One healer can focus on the egi, while the other healer can keep the other both tanks up. No tank spotting required, incoming dmg isn't very high.

Just wanted to share this alternative strategy
