Imagine farming a specific dungeon 20+ times because you need the BiS item from there and after 20+ runs the random healer from your party that does not even need the BiS item you are after, is looting that BiS item and says he can sell it to you for an ‘X’ amount of gold.
Easy subscription pay.
I love it… and all the people crying over group loot when this happens as a reason to change back to personal loot 
That aside, keep at it… some seasons I’ve done some dungeon 50+ times before item dropped…
Rofl all those conspiracy’s really go touch grass
