The Holding Out For A Healer buff was recently updated in the first 10.1.5 PTR build to provide 25% additional Honor and Conquest gains for healers as a high priority queue in Solo Shuffle.
Previously, healers have been incentivized with Field Medic’s Hazard Payout drops that provide additional gold, Mark of Honor, and more. The buff to Holding Out For A Healer looks to take a more direct approach by rewarding increased honor and conquest gains for queueing healers.
