In the spirit of good debate - I'll concede that point, but OTH, you're limited to the designer's vision of "normal" dungeon design and not able to use the extent of your imagination. I doubt seriously that any "grand halls" can or will be printed in the future without driving the price up and I don't see a lot of use for octoganal rooms in the norm to include it in a product, but I use them quite often as a storytelling device to descibe a specific type of architecture unique to my campaign.
I never said the product didn't have its place and Iare well constructed, but are far too limiting for me to use. Besides, I like creating stuff.

However, I just recently upgraded to the
Dagoom wall sets which I will arange on a blank piece of laminated battle map - so I am always open to new ideas. This just doesn't suit me at the moment. (I like 3D vs 2D any day of the week.
