Once upon a time it was common for there to exist daily (for dungeons) or weekly (for raids) boss-kill quests in WoW; think Archmage Lan'dalock during Wrath of the Lich King. User Frozenclaw, over on the EU forums, is wondering just what happened to those types of quests? Why don't we see any in Mists of Pandaria? It would be a great way to drive players to some of the lower-tier raids (such as Heart of Fear or Terrace of Endless Spring) these days, as well as a way to gain some reward for being willing to step into old content.
I think this would be a great idea! I still regularly hit up some of the initial MoP raids for valor and the like, but sometimes the queue times are, uh, depressing. The addition of an extra reward for killing certain bosses might help drive people into these older raids--great if you're trying to gear an alt in LFR, for example--and give them something nice for doing so.
Would you like to see the return of these types of quests? Would you run them if they did come back? What kind of rewards would you like to see out of them?
