Personally I think it's a result of them trying desperately to appeal to the non MMORPG crowd. There wouldn't normally be anything wrong with that really, but they've taken it to pretty extreme levels and have simplified jobs repeatedly, and made the vast majority of content in the game braindead easy. Also probably has something to do with the community being overly positive to nearly every change, my guess is they don't really spend much time looking at the places where actual criticism against the game is laid, and just aren't aware of the problems people have with the direction the game is headed.

But then again, appealing to as wide a group of people as you can is a good business strategy, I guess, if all you care about if squeezing as much money out of people as possible and then moving on to the next new player that doesn't stick around for more than 3 months
