Worlds of Warcraft should be what WoW is. Each expansion should be perfectly preserved as it originally was in EVERY regard...layered on top of one another...with ONLY characters in the expansions level bracket being able to see each other...and with its own separate AH. Each expansion should be a complete world within itself...with a transitional quest in between each expansion to move your character forward if you want to...a choice should be made at an expansions max level to turn exp off (and turn back on at a future date) or accept quest to move forward into the next expansion with all its changes and content fully intact. By each new expansion changing all the ones that came before it...it has literally destroyed the game...caused players to leave the game...and made it impossible for any new/future players to experience the game in its entirety. This is a major flaw in WoW...and the future of the game depends on addressing this issue and rebuilding the game from scratch...not just for classic but all the way through again...this time without changing it to death!!!
