Hm... it's weird I find the writing and voice acting to be above average at best, and average at worst. I feel it only slightly under performs SWTOR and is much better than TSW's which I found knee jerk hilarious, for what I felt was trying to be serious. I guess it's based all around tastes, I simply don't feel the same way you and Drake do when it comes to the PS. I think it's competently done.
The stories don't seem stock to me either. Having played Charr to the cut off point, much of the human story, and a little bit of the Asura and Sylvari. I haven't touched the Norn, but I hear that's the most widely disliked.
