When designing the standard gear of a custom regiment, is there a way to replace the M36 Lasgun with an Autogun without either handwaving it or paying 8 points to have the Autogun supplement the M36 Lasgun rather than replacing it?
I know that the Lasgun is a big part of the Imperial Guard's identity, but surely there must be many regiments that use Autoguns rather than Lasguns.
Is there a good reason (thematic or balance-wise) that you cannot pay a point or two to have an Autogun instead of an M36 Lasgun?
