So the extra cost for the commandos and Fallschirmjäger is almost equal. While the spawning from buildings is instant, it is map dependent and can be countered by mines, tripflares, wire, garrison or destruction.
The glider insertion is slow but can be done almost everywhere. If placed inside friendly territory it will act as an reinforce point.
Also commandos have a significantly lower reinforcement cost.
I think the price is quite high in the commando regiment and could be lowered to 450 maybe.
The vanguard doctrine is still a part of the game and offers enough utility for the price. But taking it out of the equation is not right.
You got your prices screwed up.
Commandos are 350. The glider is 150.
The airlanding officer with glider is 540. In the glider you can build commandos for 350.
Nades should deal damage to buildings. Especially the small wooden ones. And stone buildings are too tough anyway. Pop into a stone building and you're golden until artillery is on the field.
