I’ve been looking around to see if there are any ‘similar’ type of posts by a CM/Dev that might help answer questions or remove the idea of if certain situations are actual issues.
I found this post related to an NPC named Somnus that, when kited, it evade bugs it when kited too far.
I relate this situation with the AV Warmaster pulls where many state it is an exploit. However, if this was the case, much like fixing THIS EVADE BUG issue with Somnus, then a fix would have likely been made.
However, it shows that kiting the WM’s are not an exploit as they are not experiencing the same issue as Somnus did.
