I know this bean up before, but to make it short it can't even produce only tanks and keep up with the MP in late-game. You have like 6-700 fuel over and zero MP when the battle is over, and then you had spent almost every single MP on tank units. One simply fix that should work is to let it produce MP enough to keep intact with the fuel for building tanks. You may want be able to effort much more than tanks, but better than it it's now when you have to wait sometimes minits to be able to build a single tank, and not to forget mention your often without infantry by then.
Plz, a simple fix to make this commander usefull again Relic.
