D:> You didn't do Uldum? You didn't take the Adventure with Harrison Jones? You didn't fight the Shmazi army?
Not yet, no. I completed Hyjal, and did part of Deepholme before hitting 84 and moving on to Twilight. Halfway Twilight I dinged 85, and then I focused mostly on getting raid-ready asap.
When I had spare time, I went back to do Vashj'ir, complete Deepholme and complete Twilight. Uldum is certainly still on my to do list, but my weekends are busy, so it might take a bit.
When that is done, I'll probably go back and do the old zones all over again.
Btw, a week or so ago, I decided together with some guildies to run a random dungeon on alts. We were 40-45ish, and to my surprise, we entered Scholomance. I remember Scholomance being a decently complex instance for 5 lvl 60s back in the day. I used to farm it when you could still 10 man them. Now it was a breeze on our lvl 40-45 characters, which was a bit unsettling. The tank had never even seen the instance, having joined WoW in a later expansion. I provided him with directions and tactics, but we soon switched to just AoE zerging the place.
