I miss old Thousand Needles

Was wondering if any of you miss the classic versions of some zones, and wish u could revisit that game, but want to be able to do it in retail. I miss old Thousand Needles. I want to play it again, but I don't want to go to classic, I want to keep my toon for retail where I actually play.I would like to see Blizz put in a way to revisit classic zones that where changed in Cata, similar to how we can still go to UC by talking to random person outside the green haze of death.What zones do you miss and wish you could replay? Would you be on board to be able to toggle specific zones back to classic map instead of Cata revamp?
