I don't see the need for a separate AODwiki, too. There have been made several gameplay changes in AOD but most of the content of the HOI2wiki is still valid. It seems to be better to rework some of the outdated articles and add a paragraph which details changes/improvements made by AOD.
AoD plays very different to WiF ( My fav mod)
For instance .
Army - ( stacking penalty is a bitch)
Attack - small break out units preceded by generic attack and diversions
Defense - Rotation of org ( Let them attack weak positions and fill as need be)
Air - ( not as powerful but still critical for ports and air fields)
Attack - Sounds simple but don't send TACs in until your clear skys
Defense - INTs tear crap up
Naval - Working on it ( I don't get AoD naval mechanics yet)
