I am leveling as a resto shaman in dungeons and every time I use spirit link totem when a member is low the tank dies (with several hundred thousand damage overkill). Happened at least 4 times.
Yup, this bug is still happening, except it was the opposite in our case. Last night we had a level 70 resto shaman queueing with us in normal dungeons. I was around 78-79 I believe. Anytime they dropped Spirit Link totem, the health swap mechanic was hitting me anywhere between 5.5 million to 7 million damage lol. The first death, I thought maybe I was just falling behind on gear, then the second time, I had popped all CDS (meta, demon spikes, etc) and I was one shot the moment the totem was dropped. We had to have them stop using Spirit Link all together.
Not sure if it happens outside in the open world, as I don’t play a resto shaman (I was on my DH tank at the time), but guessing it just has to do with the way dungeon scaling works, and it’s messing up whatever health mechanic the totem has.
