We killed Archimonde like times before. Loot council decided to give me [Helm of the Forgotten Conqueror] Which is for paladin, priest, rogue. Due to an ingame bug a druid in the group instead recieved the token. The master looter did not just miss click it. When reported in game, the same standard response was given, saying how you are not able to assist.
The amount of loot one has lost due to ingame bugs really piles up. Bugs such as people leaving the group early resulting in all loot from the boss disapearing. Something you can not control with randoms in a pug that just sees they don't need the loot from last boss and then leaves, not caring what happens.
About 2 months ago i also lost Gorehowl, due to someone leaving group, and you refusing to help, even though i had screen shots of the loot that dropped. Prior to this i've lost tier 4 head and another item which i in all honestly don't remember what was.
This is not a bug report, but a post made in frustration and with hope, that the tier 6 head is not definitively lost.
