Translate this in to gaming and you might just understand how some of us feel. I want the ride there to have at least some speed bumps and left turns, because quite frankly it feels completely unrewarding to roll downhills on a straight road and be rewarded for just getting to the end. You could argue that I could build my own speed bumps and turn between the right and left lane to get some action, but that's not really the same thing.
Now, my post is not directed at MoP, it's directed at gaming in general. It's directed at how everything's become so optional (read building your own speed bumps), and how the new generation shun mandatory challenges as a result of this. In WoW, can practically stand in a capital and be teleported to your dungeons and raids all day long, sit half AFK in them and still receive the same reward as those who commit energy and not only time in to it. If you don't force what you may call a challenge upon people, many will take the lazy way with the least effort. In fact, most will since it's in our human nature.
It's great that there are optional things in-game as well for those who don't enjoy raiding and PvP, but when everything's optional even for a Heroic raider (please, don't read hardcore world first competitor) it's gone a bit too far in my opinion. You can boost your chances of loot by coins you get from dailies, and reputation might sometimes be nessecary, but everything else is thrown at you, even money for flasks and food these days. I enjoyed the nature around how raiding was in the past, the ritual of preparation that caused social gatherings in guild chat and on ventrilo. Everyone simply raidlogs these days and you don't see much of people.
Guess why? Well everything's optional, so they say "screw this" and log off!
