Operation: Mechagon, Healer Guide

Updated 8 months ago for patch 8.3.7 and Timewalking by Preston. View the change log.

This page covers healer-focused strategies for the Operation: Mechagon dungeon in Battle for Azeroth. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.
