I didn’t have any special gear sets or any socketed TW gear, I’m Shadowlands-geared only. With some experimenting during all the wipes I found out that the STATS you pick apparently make a big difference.
I was hard-stuck for like 75+ attempts until I switched my gear around for max Vers… then I “magically” got a kill a few tries later:
The explanation seems to make sense, if you armory most of the Druids that were killing it pre-nerf most of them were PvP geared/duelist geared with like 36-38% Vers. Of course, most of these “challenges” are little more than DPS races, and Vers is a flat increase to your damage output (more dmg = easier encounter).
