I have been playing mmo's for a while now from eq1 to random titles both f2p and p2p, and have done instances that take 30 minutes up to 3hrs for the average group to complete. IMO, 1hr is the perfect time for an instance. Again that's my opinion. If it's longer then that then it goes from playing for fun to being on the verge of work. When the dungeons take 2hrs or more I find myself logging in, bang out a dungeon, log back out.
What do you guys think the best time is to take to run a instance dungeon? ( take into consideration that the time is for an average group, not a tier5 raid group lol.)
