Welcome to Librarium Online!
In the Q&A section on the GW website they stated that they had plans for Crisis Sept. Here are some simple rules I made up.....
Restrictions: Fire Warriors must purchase Devilfish.
Kroot Carnivores must Infiltrate if possible.
1+ Crisis Team
Restrictions: You may not include more Crisis teams than the combined number of Stealth Teams and Gun Drone Squadrons.
Gun Drone Squadron
0-1 Broadside Team
In no way is it restrictive enough for the benefit it gives you, drop more stuff... and if its supposed to be a crisis based army why do you need stealth suits and/or drones? Wouldn't it make more sense if you needed I don't know, maybe firewarriors?
I would make the Broadsides, Aun and Kroot unavailable; they do not fit into this highly mobile force. In addition, I would stick the Firewarriors in the Fast Attack section (but keep the 'Fish upgrade mandatory) with the Pathfinders. I would leave the Stealth Teams as Elites and possibly be 0-1.I would ditch this and leave the option for Crisis teams within the Elites section. To top it off Leave the HQ in its original form, (minus the Ethereal option of course) and call it a day.
You may not include more Crisis teams than the combined number of Stealth Teams and Gun Drone Squadrons.
I hope this helped.
