Happens to me every week as a WHM. If the OT body pulls, all 3 will target me and start running towards me, if he shield lobs, only 2 run at me. Then he uses a cooldown and takes all the aggro off of me before they can get too close. I haven't found an explanation for it, I don't even do anything for 10 seconds before the pull and 5 seconds afterwards. If it was something to do with whoever used an ability last before the pull, they should be going to our SCH, since he prebuffs Adlo on both tanks for the pull, which always happens after I have everyone buffed with stoneskin. No one except the tanks are moving or doing anything for the pull.

I guess my Lallafel just looks tasty. Those dragons want a scrumptious snack.
