Before the expansions release, Blizzard stressed and stressed the idea of being able to log in on your main and always have something to do.
Did they achieve this? Yes.
Are these things interesting and fun to do? Do you look forward to them every time you log in? Not in the slightest (generalizing here).
That imo is the biggest hindrance of this expansion. There's plenty of endgame, heck some of it good, but most of it is boring, tedious, uninteresting... (looking at dailies, cooking, farms, etc...). It all just feels small scale, not very significant.
They stressed getting back out into the world and having things to do. I feel that if they made these things actually feel somewhat epic and significant, they would be a lot more fun. There wasn't much anticipation, or excitement, not much of a "goal." But this ties into the main villain/army discussion which is a different subject.
So I agree with you Trassk.
This expansion is definitely better than Cataclysm, yet has lost just as many subs. It's weird how that is.
