My group played one of the best run-throughs of Angola just yesterday -- and I have played this game a lot.
Death stacks are not an issue: as the situation develops, everyone gets them, they counter each other, and the tiniest speed bump garrisons stop them from going anywhere fast.
Two issues that we correct with house rules (happy to share) are that blue/green is strongly favored and that the special Cabinda rules are both hard to remember and result in an ahistorical outcome.
