Most of the hardcore players are get 85 now and gearing up; however I was intriqued on peoples opinions on the better of zones. Taking into account general structure, environmental detail and questing.
Personally, I found Deepholm to be the best zone, infact, the best zone in-game so far for me. Uldum however; well, Blizzard should rename Uldum " Cinematic Central ". Worst zone ever for me.
I wish I could actually enjoy the new zones, but since my server is heavily horde populated, it's nearly impossible to quest. I'm pretty much going to have to instance grind my way to 85. :\
