Thanks for responding so quick!
To be honest, I did not beat all of the dungeons. I might be able to, I don't know. If I complete the game, that's the end - I have to wait for a content patch before I can go on
I'm saving the last bits to really satiate my DD dependency, if, you know, it gets out of hand.
I'm not at all worried about content! This is the beta!
I'd like to mention, though, that challenge and difficulty are different things. Some of the 72 DD alpha victories (twice, btw) weren't overly difficult, just a challenge to overcome - some of them were very difficult. These last two beta dungeons are ridiculously difficult, and there's nothing (obvious?) to unlock if I beat them. That's not a negative thing - they need to be that way so that imbalances and exploits can be discovered. I'm just not driven to continually attempt them just now.
