Turbine has a convenient player/dev Q&A page, so they can avoid answering the same questions over and over.
This one particularly amused me:
Question Title: Where are the Dragons?
Question: I understand why you have not picked up some of the traditional “D&D” type monsters. The game is fresh in this regard and I applaud you for your innovation…
Any chance of Dragons entering the world anytime soon?
Name: Jason Booth
Answer: none what so ever.
I have a suggestion. If you want clich\’c3\’a9 “traditional fantasy”, there are plenty of other games which cater to that brand of generica. Fight dragons with your drow elven princess warrior priestesses there.
