Would like these idea more in the futher future... since lets Revamp Kalimdor and Eastern kingdomes making it a Grapic and lore revamp pushing the story forward showing the "Battle for Azerth" battles and wars that we Read about in the Mission table... so much lore and Interesting story to explore just waiting to be used by blizzard...
1. We need to make the Leveling good again, making the Lore make sence and giving new players a good leveling system to enjoy (Not gonna explain more since I have a very complicanted idea on that topic)
2. Then Since in Cataslym the team was 10 times smallers and the entire Azeroth Revamp was rushed... everyone zone had a half kind of work on it... now with the bigger team and Beeeing ahead of schedual, we can make a real and good Revamp that would scale the entire continents of Kalimdor and Eastern Kingdomes up to Max level making it all Max level content... just think abou it "so many quests (If you like to do them all) this way every player could choose where to level and do so again on many many alts"
3. Starting with a Azeroth Revamp, we could then Go for Outland then Northrend, then After that, It would be cool doing other stuff... its just that we need to Put the Lore in the game straight again... as it is now New players get pushed away... and New players is VERY IMPORTANT for a game to survive and give it a future.
4. Something that would be amazing would be to make it possible to only level in Azeroth "Kalimdor and eastern Kingdomes" to get to Max level, that way, everyone can choose where to level and if they have many alts or like another expansion they can leave Azeroth and level in those, Making everyone happy and not forcing anyone to do stuff they would rather not.
To me and to all of us, Choice is the very essence that drives us and that makes World of Warcraft so great, would be even better with more Choices
