I was SFK today and there was a shaman in the group. We reached the trash groups consisting of 4 gargoyles and in the middle of the fight the shaman, he was elemental, used thunderstorm. The adds flew over the battlements and evaded. A few seconds later they returned to their starting location including the emote to awake when you pull them and attacked anew.
This could be used to kick them over the edge and run past them before they reset to save abit time.

The thunderstorm kicked them into different directions on the pic because the shaman was right in the middle.
