I won't argue with you there daniel, you do make a good point. However what a dungeon randomization tool does provide is easy access for gamers(who don't have the time or know-how to create masterpiece dungeons) endless hours of replayability at the click of a button and the toggle of a few switches or the sliding of a few bars to specify the generic basic requirements of the dungeons before randomization was to commence.
Handcrafted levels or dungeons will always achieve a level of detail and creativity that can never fully be realized when generating random dungeons based on a series of guidelines the player or devs specify that are needed to create the random dungeons. But making handcrafted levels takes time to finetune them and hone out the details of the dungeons, time and skill that not all players would have the time or interest in doing.
Still, a level editor being provided to the community would be ideal, as well as allowing players to share their dungeon creations with the gaming community, well that would be sweet. Random dungeon generator would be awesome too, but first let's see the game come to fruition, then things like level editors and level generators can come later if the dev's decide there is a high enough demand from their already growing and adoring community to add those ideas to the game after it's been released.
The suspense is killing me, I must have this game NOW!
