I never implied that doing what the players wanted worked for Blizzard, merely that they did what they thought people wanted. Whether for good or worse, that's what they did. Clearly, as subscription numbers have shown, it was for the worse.
And yes, I agree that in the aim of balancing, they have made some very... questionable choices. Which is why, like I said, I find WotLK to be the best WoW got in terms of pure gameplay. It really does have everything an MMO should have, and is excellently balanced as well.
Would removing flying mounts and teleport hubs (Looking at you Dalaran!), RDF, BG queueing from Honor tab help? Maybe, maybe not. It would certainly add to the roleplay and adventure aspects of the game, that's for sure. I would personally welcome it, but I know most won't. But I don't think that me wanting these things is as high a priority as balance in the game, or smaller raiding teams.
