Hello, after being leecher for over a year now i figured it was time to contribute with my exploits, so here goes:
When you pull the boss from its original zone it does not spawn trash mobs.
Example: pulling out XT out if his room into the corridor (in the middle of it) results in no trash spawns, they still spawn but in the boss room and do not attack the raid. The best way to do it is usually using a hunters pet.
Don't know if you already know this, but i havent found it posted here. If it is a repost say so
PS/Edit : I would appriciate it if you were to atleast comment
