And, as a personal opinion, I hate the options nesting into battlesuit choice on Commander. I do know it's the only way, I just had to air it. Maybe a little hint in the armour group name, like: 'Battlesuit (options inside)'. IDK.
Other than that, @efalsken - nice job man! I'll do the changes now and send it to BSData master. I feel you've done near-perfect job. Perfect enough for blue communists we are.
Also, why did you bubble up Drone choices for Stealth/Pathfinder/Strike/Breacher teams? It's very unclear now. You have a group 'up to 2' which throws error when you don't have team leader. Count me against that. Either append some text ie 'requires leader' or nest into leader.
still not convinced how to do the Combined Firepower. And don't know how yours reacts, but in mine Cat Editor, after reopening, modifiers on root rules always get lost. They stay in the file, but don't display.
the part you missed probably is in the third paragraph on page 71. Second sentence, the last part: '... whose slots are a combination of specific Formations and Army List Entries instead of Battlefield Roles.' - Drones and flyers are just that, Army List Entries as Auxiliary choices.
The same is Command choice. It's not a formation, it's a collection of ALEntries. No additional rules. Which kinda makes me sad, as everyone up to us had some.
