Leveling is good to do once or twice, nothing new if you did previous expansions.
If you like questing, guess what ? you can quest untill the next expansion if you want to.
Raids are well designed and fun to do.
They have tried to make alot of specs raids viable.
On the daily subject;
Blizzard already made it clear that they are looking into alternative ways to get rep, and they should.
I bet they didn't expect the shitstorm they created with locking everything behind dailies (Cooking, proff recipes, Vp gear and even jp gear at the start).
