It is the last lv 79 msq quest if i remember correctly. Though if you want the armero mount you'll have to do all of the role quests. Still it's a bit of a wait what kind of moment. Many aren't going to stop their msq progression just to get another job to 80 just so they don't miss out on the xp they give. Like everyone knew that we'd have the roadblock that is finishing the role quest, but I don't think anyone would have guessed it'd be how it is.
