The WoW Experience

This is gonna sound a little crazy but just bare with me for a minute.

Ok so imagine a server you could go to and have the real WoW Experience, by this I mean 1-2 Realms of each patch that you can lvl max lvl on and do that patches achs/engame content until your #1 bored with it or, #2 finish it. I would love to have a Vanilla server and a tbc server to do this on. I could start at Vanilla and lvl to 60 then do all the content I could and transfer to the next patch thats on a different realm, I would then lvl to 70 on that realm and do all the content or w/e i want till bored then transfer up a patch again. You wouldnt have to go up 1 patch at a time either u could go straight from vanilla to MOP if u wanted to, this would bring alot of people because no servers have done this to my knowledge, this also brings the possibility of people donating more, maybe i want to be BIS warrior on vanilla for a few months then on tbc then on wotlk and so on. Some people would pay for that and we would get a more proper Wow experience instead of what you did on lordaeron wich was not like how the game was at all... u could actually play each patch and just transfer up whenever u want to but never back down. think about it lemme see some comments! If u see anything i left out or some things that would make this idea better please add ur input.
