considering the amount of players using the duty finder system, it's probably programmed keeping the KISS principle in mind... (Keep it simple, stupid). Sure it would be nice to expand upon the functionality of the system but it would probably exponentially increase the strain on the system and the length of time required for matchmaking. at this point in the game's lifecycle I don't think we're going to be seeing a whole lot of ground up remaking of existing systems. tweaks here and there maybe, but things I think at this point are 99% set in stone. big thing upcoming is the expansion of the party finder to allow for the 48 man preformed groups needed for 5.45's Delubrium Reginae savage dungeon.
