Completely agree. This isn’t the most convenient thing but I found that by having a guild mate on his Alliance tank and me on my Horde tank, we could communicate to everyone how it works. Actually setup macros to streamline things. This made the process significantly easier but of course, that doesn’t always work. Even on the same faction, some people just don’t listen.
Unfortunately, it only worked around 50% of the time because all it takes is a single person sitting by the cave entrance or in the center to bug it out. Every single person has to stand alcove in front of the boss or it’ll bug out partway through.
This should not have gotten through Q&A. There are only three excavations on the entire island and Blizzard could have just killed the mobs a few times to realize this one was abhorrently bugged.
