Coming Back?Follow

I quit WoW shortly after Cata, and then MoP was announced, and I was glad I quit. I've tried several MMOs since. SWTOR was fantastic at first, then went F2P and went down the tubes, IMO. Then I tried GW2, and it was fun for a while, but I couldn't get into it like I did WoW or even SWTOR. Just recently started playing FFXIV: ARR and I'm having a blast, but I'm starting to get nostalgic for WoW. How much has WoW changed since the end of Wrath/start of Cata. Is it worth coming back? I've heard MoP has been much better than Kung Fu Panda and Pokémon that everyone thought it was going to be.

Any advice anyone has for someone thinking about coming back? I know this ZAM account doesn't have many posts, but I couldn't remember my old EMail that I had when I was posting more often here.

Thanks in advance.
