I play perhaps 30-40 minutes per day on average. I'm currently lvl 39 (resumed from level 32 in 1.0), and at about the level 28 point of the main story. I enjoy slowly progressing through the main story quests, but when I get to a dungeon I know I'm stuck until I get extra time to sit down and play it.

When I DO get to a dungeon and use the DF to get a party (thankfully I never need to wait since I'm a Tank), there is always someone in the group who knows what to do at each new boss. So we never wipe or fail (so far). This is taking a lot of the charm and fun out of doing these dungeons for the first time...
