I've been meaning to mention this for some time, but have kept forgetting to bring it up -- I hate the idea that the Jedi Order had a council prior to 3986 BBY.

I like how the TOTJ comics depicted the ancient Jedi as being largely decentralized, with masters only coming together to deliberate in times of great crisis. Making it so that the Jedi have always had some central leadership in the form of the Jedi Council is just another stupid retcon made to force the older stuff into matching the prequels.
