So, on the strategic level we seem to have a little problem.
Our Legion can hold something for a while, from behind strong fortifications at least. That gives us enough time (hopefully) to deal with an attack against a defended position of ours by using our airforce and PCs.
But on the offense we have only our Airforce, nothing to actually take, hold and loot a place we don't want to see reduced to rubble.
@Azel correct me if I'm wrong, but I think we have a total number of Praetorians that comes out as about 1 unit in this system?
That aint much.
Looking at our totals we have much more Construction available than anything else, so making cannons and mechanising our existing Praetorians seems like a good investment.
Ist that possible? Upgrading an existing unit of Praetorians to the variant with tanks and big guns at a price of 30 supplies and construction capacity?
That Fleshforge has to be upgraded and luckily it can, we have lots of Ward-space left over in Gorgossos.
Aside from that, in terms of capacity Heavy Undead are more efficient than Praetorians (same cost in supplies, but Praetorians require training as well as Fleshforge), but since we can otherwise only use our training on relativly useless regular Legions, we might as well build more Praetorians. Mechanized they are universally useful.
