I am not certain that 'way too complex' is what was meant -- perhaps he meant not appropriate to simulate the command decisions of the general. Integrating the pikes and muskeeters by intergrating two normal sized units into a large unit might be a reasonable programming possability. Probably too late in the development cycle to do it for S2TW though. It would be nice if such integrated formations were an option though. If done properly, the AI could then do the same.
