MMORPG was kind enough to give their fans a video recording of their interview with Turbine. While there is a lot of the same information I think seeing a Turbine employee talk about the product and to hear the tone of voice really helps calm the nerves about the expansion. One thing I would like to point out was the confirmation of more levels for your legendary item. I am glad they are expanding the max levels for this after a while of being stuck at level 70.
Another interesting part was when they talked in depth about mounted combat and being able to see the excitement on the faces of both the interviewer and interviewee. All in all I think this has made me much more comfortible with my purchase of the expansion.
