Ignoring the loot, the credit for killing these bosses isn’t registering correctly. It took about 30 mins to get a group together through LFG and waiting on them despawning and respawning because a random pulled them and flew off, only to not get credit for both bosses on the world quest.
I killed both in a raid group, the pop-up like “Zaqali Elders defeated” popped up, DBM confirmed I killed both, but no credit for Vakan. This WQ is such a pain; please fix it.
