For long time I did not mind the dailies and did them diligently (including Shieldwall). Since the latest patch I cannot seem to bring myself around to doing those anymore, I feel fed up with them. I have logged in with the intention of doing them, but before I even picked up all the daily quests on Isle of Thunder, I'd release a sigh and realized I could not be bothered.
One thing i that I don't like the way they changed mages this patch, I don't care about the loss of damage (at least not much), but the playstyle is boring now. This puts me off from raiding too, even though I recently joined a new raid group and we were doing OK on 25 man really. Last three weeks I only entered LFR on my alts for that reason. Haven't done any raiding for 3 weeks on my main.
Alting is not much fun either. This used to be popular with me (normally I would have 8 classes at max level by now), but the daily and rep grind is just too much really. I'll admit that the rep grind has become much easier with the farm rep and the doubled rep XP, but still.... it's the daily routine all over again. And then still you need the VP... Which means you cannot alt comfortably on a casual basis either. If the rep rewards would only cost gold if your main character had already unlocked them or something.
Besides that gearing is just too slow, it still can take several weeks because you have to go through the lower raid instances first for lots of times before you can move on to next. It's just too much. I have grinded the old raid tier on my main for weeks/months and having to do it for the same amount of time on my alts is just..... meh.
Maybe there's too much to do and I cannot choose. I'm not sure, but the fact is that I am always wondering what to do. Until the release of MoP I never had that. It's quite contradictory in a way, There's so much to do, yet I cannot find interest in doing any of it at the moment, not even achievement hunting which was always a favorite pastime for me.
Dunno what it is, I decided to play some different stuff for a bit and do less WoW (came a bit natural really). But I seem to be enjoying myself more at the moment playing SimCity or even Farmville 2 for that matter...
I'll see how it pans out, but for me, I think it's the fact that I feel I have to do much more than in earlier expansions to experience it all and that it is more tedious to do it (especially if you like to play alts). I have a job already, don't need another one. And I do know that I don't need to do everything, and I don't. But I just feel that progression is lacking at them moment, it all feels to slow really...
