Molten had such an "idea" with a server which was equally high in queue times and did it over a mere ~10% difference vote, messed up multiple servers and their economies. The server which was "progressed" if you can call cata a progress of any kind...never saw the same population again. People don't know what they wish for until they experience it, granted...the server was buggy as well.
Here you answered your own question and you'll understand it better if you keep leveling and trying out different classes. If you still have the need for the next expansion try it out on a populated server(can't advertise) and see what it looks like, some stuff from what's to come is already available (xmog/models).. Each class is still unique, elites and rares are what they are, not everybody and their pet/battle pet/grandma has a heal...and the city raids are existant. I can only speak from experience up to MoP and believe me, up to there you're not missing out on anything half decent.
As for OP, make a progression guild or check if one is recruiting(usually guaranteed to find one in global), no need dooming us over your boredom.
