In reply to the above highlighted: when you've gotta' farm upwards of 70 kills in some cases (RNG is a bitch), you're just going to leave after the one you need. Whilst I completely understand it's a piss take for the rest of the group, and I do honestly feel bad about it because it's so frustrating when it happens... there's just no way anyone is going to sit through the entire dungeon that many times. Especially like Theatre of Pain where it's the 1st boss, which is 5 seconds into the dungeon. At least in my case, there are so many DPS in LFG you'd generally fill that spot instantly.
Blizzard should have made it a guaranteed drop (make it Mythic if they feel the need, doesn't matter to me) from the LAST boss of a dungeon or drop fragments to make whichever legendary you want instead of a low chance from whichever boss your spec wants.
