Just downed Attumen in mythic Return to Karazhan for the first time since the reset and he dropped no loot. He wasn’t even clickable to grab anything off of. Opera dropped loot as usual and then I headed to Attumen.
Please fix this, this is one of the things I’m farming during Collector’s Bounty (the Midnight mount.)
Engage the boss before 1 shotting him.
Even just body pulling him is enough.
Yes, Blizzard could (and probably should) make it so that they give loot even when insta-gibbed, but until the devs do, you can ease your own pain by following that little piece of advice. It’ll cost you maybe 2 seconds.
I haven’t had this problem on any character for the past several weeks, just today.
What was the class, and what attack did you use? It seems to matter.
