The OP has a real point that so many of you are dismissing after flying over at 30,000 ft. But think about it. This really is a big deal. From high up, it may not seem like engaging micro transactions and selling max-level characters will impact the game for others. But the truth is, in the details, it already has.
The game is constitutionally different. So much of the overall experience has been removed. Leveling is skeletal. Interaction is minimal and superficial. Immersion is gone. As a result, the community shifts from deep and dynamic to shallow and entitled. Instead of focusing on the former, Blizzard reinforces the latter. And thus, the game begins to change. The journey is minimized and defined by the reward. Justice/Honor points for gear, mounts. Valor/Conquest points for more. LFD to gear up. LFR to gear up some more and satisfy the urge for more gear, which created an even greater urge for gear, more opportunity without context and moving the game further and further away from substance - the kind of substance that kept people playing for a half-decade or more. The game is different. The community has changed, with half expecting opportunities to be spoon fed instead of being a part of something bigger than themselves, and the others getting sick and tired of it. And Blizzard wonders why they are having difficulty keeping players, old and new alike.
So, yeah, the OP has a point. This whole micro transaction model and potential max-level sale is only a bad thing and signifies that what made WoW wonderful is permanently gone. What a shame.
