You’re entitled to be upset, but this is all bordering on hyperbolic. Unfortunately, this seems to stem from queueing and then having the raid group requeue after folks left - and that can bork out the satchel for you. The confirmation pop-up that guarantees that you’ll get the satchel doesn’t necessarily pop in LFR since you’re already in there.
This is the comment in question that the support article is pointing to.
Now. If you don’t like how this operates and you’d like to see a change? You will need to post where the Devs can collect feedback. This forum is unique in that it is not one of them. I would suggest you go to the Dungeons/Raid forum with this over the chaos that is GD.
Holy moly - the thread you’re even referencing? It was three years dead before you necro’d it. In the future, please just create a new thread.
