Their dps adjusts to your own, and the dungeon runs always take approximately the same time, around 20-25 minutes. Which is what you're gonna usually get running the dungeons with actual people doing supposedly good aoe dps. But without queue times, or terribad players, or drama, or loot grief. The Trust system was possibly the best thing they added to the game in ShB, and I haven't done a dungeon with a group since the twinning. Some people just have to do content with other people for some reason and that's fine but the system itself is superb for what it does, and I rarely say that about anything new in this game.
