I am tired of the gogogo nature of WoW lately.
I would love to see an expansion down the line that:
1.) Has slow levelling, maybe 20 levels or so that takes 3 months at least to reach max
2.) Large open zones so that travel on ground mounts does not feel like gauntlet runs. Open like Tanaris, Westfall, Barrens and Winterspring
3.) Guild or class halls like the order halls we have now, but no mission table
4.) Dungeons and raids as we have now with some villains, but not necessarily the great evil that wants to destroy the world. More like Van Cleef, etc.
5.) Flying when you reach max level without having to grind reputation. The rep grind it just there to keep us subscribed, but the same effect can be achieved with the slower levelling
6.) World quests as we have today
7.) World bosses as we have today
8.) Content that don't force people into activities they don't enjoy like raids and pvp
9.) Professions where quality gear can be crafted, but will take effort to do, like having to gather tons of mats (like it was in Vanilla and TBC with the enchanted bars and leather, etc.)
10.) Grinding levels as an alternative to quests, for those that enjoy it
On the other hand, maybe the game is just fine as it is and I am tired and need to take a wee break
