Game Master is severely hamstrung by how stupid the AI are.
Can't fly helis, can only drive If given an A to B route on a main road, unable to figure out smaller roads or driving across any terrain that isn't a paved road, when they are on a paved road they all crash into eachother or roll themselves taking corners too fast. They barely know what cover is how to use it.
Game master/custom scenarios get so repetitive so fast because it isn't possible to do anything more complicated than just objective assault/defence scenarios and it really needs urgently addressing.
