I've collected a lot of positive fanfare from this idea already, so I'll just go ahead and propose it.
---------------------
The Idea:
Permanently spawn random bosses and/or mini bosses all over all the maps every friday-sunday at couple hour intervals every weekend from here on out.
The Need:
Players shouldn't be bored in a game, there should always be an available slew of things progressing or happening to keep the player entertained. I personally find myself AFKing whenever I log in, so having another purpose to play the game would be welcomed and is actually past due. I believe having bosses constantly reappearing every weekend would just be a simple feature that would add to the variety of ongoing things for a player to participate in and enjoy with random other players and friends in an open non-instanced environment.
Ultimately, this idea would be just another avenue, for you the developers, that would allow the players to create more social interaction in helping each other out in some intangible manner. I can't help but remind you of how critically important and underrepresented the social value element is on a game's ability to survive.
Implementation:
Shouldn't be too difficult, you could probably just tweak some existing boss spawning event scripts. The only real effort from you guys that would be needed is to promote it once in a while to garner interest for the uninformed and to add some on-screen preprogrammed messages similar to those that currently trigger when a theme battle is in progress.
