Ok lets say you are being tank pushed. You forgot to get corsairs. Your in trouble. What would be cheaper. Going in gung ho with goons and zelots? Or stasising the tanks then goin in, wasted any support then taking out the tanks.
Or what if the player walls off.
To get inside his base the only 3 ways are to run in, again, gungo ho style, into his wall in an attmept to break it, or you could hallucinate arbiters up teh ass, run in and recall into his min field, or build shuttles up the ass and drop in his min field. WHich one do YOU Think would costs less. 3 arbiters or 15 shuttles.
