Player left Mythic before completion. He still got the loot

I was in a Mythic +6 Mists run. We wiped 2 times on the last boss and a hunter just left the group after the second wipe. We go on to down the last boss anyway. When we opened the chest , no one got loot. I was then informed by a guild mate that the player who left early will have that piece mailed to him. That is total BS, if a player leaves the dungeon before completion then they should be ineligible for loot.

i feel you. on the other hand, if the player who is no longer in group is not eligible for loot, what’s to stop a group of 4 guildies from kicking the pug dps right before the last boss to keep the loot “in guild”?
