Historic articles are mostly not up-to-date articles which are not relevant anymore. If possible we try to modifiy the articles to fit the current game, but in most cases we move the article into the "Pre-NGE" category.
Star Wars Galaxies was undergoing big changes in the last years and most of the changes hugely affected the complexity of the game (and our Wiki of course). Just when we were about to capture all the complexity of professions, crafting and so forth, two things changed SWG significantly:
CU[]
"Combat Upgrade"
NGE[]
"New Game Enhancements"
This was a huge overhaul to SWG, changing the fate of the game forever. It received both criticism and praise from the community. The skill system was replaced by "9 iconic professions" and the whole interface was completely changed.
