Fel Armor, Zephyr, Acid Rain even pretty far away all body pulling the boss and not allowing anything conducive to be achieved. Sometimes if you play on a warrior you can even Heroic Leap to the platform near the boss and body pull from the splash damage (kinda far) where someone else would not regularly.
The hit box is just a bit large, and especially auras shouldn’t pull the boss so far away like that, it makes people mad and impedes progress. They even started to look up fel armor and zephyr as spells to see how it could be possible, not something I’ve ever encountered. To add to that, people begin to get nasty.
