not really a question but just a way to pick the brain. if you were in charge of the all military decisions for the dominion and you were completely humiliated in the defeat fighting kerrigan and you were now able to upgrade your units, wouldn't you upgrade the siege tank to be able to attack air??? i'm not saying that it should fire missiles but i'm saying after hundreds of years why wouldn't you think to spend that extra 50 minerals to put a .50 cal gun on the tank? even if it would not be very powerful vs heavy air units you would still be able to defend yourself at least a little from light air units. and if things got close you could fire at very close range when sieged. just my thoughts.
