Are the availability lists for the Force Manuals meant to be tied to the specific formations they're listed under? Or is it simply how they were organized this time around, and any unit on an availability list can be used for any formation it could fit into?
If the latter, why change it? The old wall of tables from the Combat Manuals, with multiple sorting methods, did take up a lot of space admittedly, but it made it so easy to find exactly what you needed, pretty much no matter how you were trying to build out your Formations. The new method feels clunky and slow by comparison, flipping between pages to find an oddball Brawler you like, or a Missile Boat you know should be available and that you have a model for but you're not sure what Lance it would be under.
