Indeed, so much more challenging that it was in the Beta!
In the beta I steamrolled everyone and cleared the wildlands almost single handedly.
Now I am playing at Beginner (I am not that good yet) and while I am winning, the world did gave me a hard time to expand, and the wildlands are SO hard! (Not that that's bad, it's what I would expect from such a place.) 
I fyou guys can only keep improving performance, I would be thrilled.
