When I did this today after reset, I switch to all my characters and got in my daily quest, but my 57 rogue was unable to do so. I didn't think much of it at the time. Then when I log back on my priest, I get a rush of whispers asking why they weren't able to get the quest today, when they were able to on previous days. I put 2 and 2 together, converted it into Gnomish Binary, suffered through hours of calculations, and then finally came to the conclusion that Blingtron 4000 must have been stealth nerfed in that his daily quest now has a level requirement.
All I can figure right now is that the requirement is less than 80 and higher than 57. In any case, this kind of ruins the appeal of having a Blingtron when I don't have a dozen level 11 pandas surrounding me when I drop him. I imagine this was done to prevent someone from dropping a Blingtron in Northshire Valley and spam creating humans to get many turn ins done before he disappears every 4 hours. I would think it would be less of an annoyance to players to just scale the items in the gift package to the player's levels.
All in all, even though I only lose one attempt per day, I'm still sorely disappointed.
