As Blizz keep saying about complaints re CRZ, where people at every level face the problem of many people doing levelling quests, it is an MMO. MM = massive MULTIPLAYER. Switch to a low population server if you want less competition or do not do them when everyone else is doing them - get up early, most people say they finish these fast but they do not always play when the rest of the server does. There is no way you will get a phased zone just for you, although you may not agree, you are simply, like the rest of us, not special enough

And it does seem you think it is a case of 'gimme gimme' - what else does asking for a whole zone to yourself imply? The expansion will be around 12-18 months at least I guess, you have plenty of time.
You, as many people, are not used to working for something, and working means that, if you want something you put in the effort. You don't want to put in the effort you have to accept you will not get what you want unfortunately.
