The issue nobody wants to address

[Arashmin]

My guess is the same people who are upset about anything more than 15 minutes in a dungeon complain about a lack of content. MMOs... social games right full of anti-social people.

That's a mighty bold assumption. I'm fine with dungeons taking up to 30 minutes or so, especially in DF, if it's for relatively sane reasons. However I'm also in the 'lack of content' camp. Also, I'd argue against MMOs really being all that social unless you're talking about the highest-of-high-end with complex mechanics, because otherwise everything you need to know is telegraphed in an easily observed and understandable way that you should be able to learn to do by yourself.
