In the Diablo 3 expansion they introduced a bounty system, essentially when you enter a game you're told to visit random locations in the game and kill this guy, or save this chick, or complete this event etc.
Wouldn't this be a great system to get people out of capital cities and into the world (of Warcraft, huehuehue)?
The difference from daily quests is that these events would require groups to complete as they would not be soloable, but not necessarily super organized groups, just maybe 3-5 people so as to have some CC or some healing or some tanking. The events would also be diverse since they would be spread on every world, every continent and every zone, randomly picked each day (3-5 zones).
The rewards would be substantial enough so that if you choose to pursue bounties instead of daily quests you wouldn't feel like you're losing something, and completing 3-4 bounties a day gives an extra cache of goodies.
The bounties could also be PVP objectives to promote world PVP, kind of like Isle of Thunder, you can choose whether to pursue PVP or PVE bounties, or a mix of both. Since PVP bounty zones would be chosen at random each day, maybe 3-4/day, this would also help coalesce more players together to fight, instead of spreading them all over.
I mean don't read too much into my post, just add improvements to anything you see which might needs improvement.
I vote yay!
