Which lore should be used ?

With the perspective of writing fictions and/or role playing on an older version of World of Warcraft, an interesting question appears : which version of the lore should be used ? What should be canon ?
We have several options.
1. Actual (6.0) WoW lore, which is still completed by Blizzard at the moment.
2. Burning Crusade (2.0) lore : when 1.12 was out, we already knew the new stuff about Draenei and Blood elves. So the Outland lore would be canon, but nothing after it.
3. Original WoW lore (1.0) : fits with the books you can read in game.
Several changes here :
- All orcs were born green. No exception.
- Illidan is presumed dead. The Blood Elves are in Outland and no one knows really what happened after that (TFT). Quel'thalas is ruined by the Scourge.
- No one knows what happened to Gilneas and Kul Tiras. As far as we know, it is not destroyed and the two kingdoms are fine. (except there is a new leader in Kul Tiras as Admiral Proudmoore is killed by Rexxar in TFT.
- No draenei & Draenor retcons : the draenei are native from the mushroom covered world of Draenor (which is also know as the Red World), they is only one version of them (the ugly one). They built crude cities within the world's towering cliffs and peaks. They have no links with the Eredar. The Eredar (along with the Nathrezims) corrupted Sargeras, not the opposite.
- The Well of Eternity was a huge lake (almost a sea), not the tiny pool you can see in Cataclysm.
- The Maelstrom is huge, not the tiny thing from Cataclysm.
- Azeroth is both the name of a human kingdom (where Stormwind is) and the name of the planet.
- Dragons usually kills you at sight. Not many exceptions. They are not your f*cking friends, they are big lizards who don't care about your little mortal life.

4. Create our own lore (which is a difficult operation ideally involving a wiki and administration to keep the lore consistent).
