So I just came back to the game after a year or so hiatus. I saw the end of Cataclysm but my working life left me in a position where I couldn't commit the time anymore but that's changed again and I've decided to pick it back up. Because of this I haven't seen any of the changes and haven't read a patch note in well over a year. Before Pandaria I used to raid hardcore.
So what have I missed? Are there any definite factions I need rep for like Therazane or similar? Any decent mounts worth farming? Any quest chains that open up something I'll want? Any achievements I should check out? I'm open to anything and everything. I more or less haven't touched the expansion.
If you didn't play the last year what would you want someone to tell you about?
Thanks in advance!
