Just a forewarning that on some end boss mobs for the POP signature quest, if your pet or swarm pets get the kill shot on the boss mobs, you may not get the items that are needed to update and advance your quest. Happened to me a couple of times and had to redo some of the zones. Gaukr Sandstorm in Torden Bastion of Thunder wont give you the key as an example. Just wanted to give a heads up.
Devs are aware of it and are looking at a fix. Not sure if its implemented yet with the downtime or not. I put warnings in discord as well so hope folks can avoid it.
