Edit. Did you go to ragnaros right after or not?
I remembered that there was respawn issue if you did not talk/meet him later in vanilla.
Seems so. They won’t punish you for abusing it, since they have do nothing for those who been doing it whole time. Streamer been streaming that and no actions from blizz.
Never wondered how there are so many with MC gear?
They found how to duplicate that bug on purpose and blizz has done nothing about it.
Although I remember in vanilla majordomo spawning back was a thing but chest did not appear even if you killed him again.
Only on cases that you don’t meet him at ragnaros after you kill him, if I recall right.
But unlike back then, people say chest spawns each time with loot.
