TL;DR At the end of post
This is an idea I had and thought it would be kind of cool and would tackle all of the complaints at once. I've seen on forums posts about "Progression Servers" in which the server forces players to play through all the expansions again, this would cause the developers to send out content a little at a time to make it seem like a re-release of WoW. In my opinion, with the amount of time and effort that this would take it would not be worth the outcome. The people who want vanilla servers would stop playing and would start the circle over again. On the other hand Blizzard releasing Classic servers opens up room for everyone that was in love with any other previous expansion to come up and say "Where is our BC, and WoTLK servers?". There would also be a drought of content in the game in a very short amount of time. People who loved Classic unfortunately know the game far too well now, they would burn through content far too quickly. Some of these people, once they are fully geared or are done with the PvP will demand new content. (Essentially Runescape Classic if you have ever heard of it)
My idea essentially involves a server where instead of forcing people into playing the same content over and over which would annoy some, or force people to play different expansions which would annoy the others is to
give players a choice. What I propose is a server where when you log in and create a character it would ask you which expansion you would like to play. If you choose Classic you can experience killing the Ragnaros for the first time again, going through the gearing process of arriving to that moment. However if for whatever reason you are bored with the content or just feel like moving on, you can go to your in game menu, and open up a menu that allows you to pick what expansion you would like to move to. So if you would like to move to Cata, you can experience the map changed by Deathwing. You would be able to choose Any expansion moving forward but not choose to go backwards however the newest expansion should not be playable on these servers. It would overwhelm and cause too much lag on these servers and there are far too many servers where you are playing the current game to allow these on what I am calling "Progressive Servers".
TL;DR
- Players choose what expansion they would like to play in character creation screen.
- Players able to move on to the next expansion through in game menu.
- Expansions would be set to the last patch of that particular expansion. (before the next expansion's Pre-Patch)
- Players would be unable to play the latest expansion on these servers.
With this idea the players would be able to play Classic, BC, WotLK, Cata, MoP, WoD, (and when Battle for Azeroth comes out) Legion, and not have to add/develop new content that is not already in game.
As to how this could be done is a completely different discussion,people who choose different expansions could be phased, or some content locked or something along these lines, but that is something I feel the community would be able to help figure out.
