You claim nobody asked for dailies, yet here they are, appreciated by a lot of people who enjoy doing them. You don't like them, so what? Others do so your point is moot. There are those who don't like dungeons, according to you Blizzard should only make dungeons because that's the only content you seem to like, couldn't others claim this though? That all dungeons are a waste of time and resources because they aren't fun, and Blizzard should make other content instead?
If dungeons, dailies and LFR doesn't feel worth doing because it's not rewarding enough (which I really don't understand considering it equips you in a full set of armor, which is its entire point), then I really don't understand why you even still play the game. It sounds to me like you have simply outgrown the game, and not yet realized it. I say, move on, there are other games out there that I'm sure you would enjoy.
I highly doubt you know anything about whether or not they have actually hired people. Yes, the game has been declining in subs since Wrath, which is exactly what I said. But the game as a whole is still standing strong as the biggest MMO out there, which is pretty damn impressive considering how old it is.
I'm not defending them for their sakes, there is a lot Blizzard does that I do not agree with, in this case however, I happen to disagree with you.
Go ahead and unsubscribe, can't say I'm going to miss you in the game.
