I lost 4 of them last night and 1 today. By lost I mean that I didn't even get them and they haven't been sent to me afterwards in the mail either.
I signed up as a healer, my loot spec was set to "Current" so it was on Resto. But I haven't gotten any of the loot bags for signing up as a healer. This is the fifth time I don't get one of these bags and I'm pretty sour about it.
Instead of waiting a week for a GM to answer me about it I thought I'd ask here if anyone else has this problem.
