I've been feeling this way for a while. The model of having short dungeons with extremely low drop rates that are supposed to be run over and over and over and over and over in quick succession is extremely tedious and not at all interesting. I would also be in favor of moderate lockouts (a couple days for most things) with much higher loot drop rates. Extremely low drop rates are not a substitute for interesting content.

Hopefully this dungeon/loot model is just a result of having a small development staff dedicated to adding content to the existing game, and things will change will 2.0. If not, I fear for the future of the game.
