I've been confused about this for awhile. Are the Advanced Archetypes additions to the standard Archetypes or do they entirely replace them? I've looked at all the Tomes and none have given me a clear answer one way or the other.
To give an example, I wanted to make an Alpha Legion Sorceror for a game, but just before it started up Tome of Fate was released. I thought Sindri Myr was a pretty awesome character in Dawn of War so I had wound up combining the Starting Archetype, the Chaos Sorcerer with the Advanced Archetype, the Alpha Legion Chaos Space Marine. The game is over, so it's a moot point, but was it against the rules to do this? My character certainly had some extra tricks but he never felt terribly overpowered compared to the others were doing.
