There is still no cost effective ground based aa solution. How is the current stance on air? After having no chance at all vs people who just go 90% air I feel either I am doing something wrong or the removal of the aa bot still is an unfixed problem. Mainly the problem is that you can't defend your ground units without your own air due to the fact that the aa vehicles range is so small that your opponents two dozen bombers will drop all their bombs before you even hit them. EDIT: To further explain the problem as I perceive it: AA units may have a direct chance in a fight with equal metal invested in the AA unit and the air units if it goes lucky for them. If the ground army is unlucky then the bomber splash of one flyby will completely obliterate the whole army. Even if equal metal aa wins vs air you never have equal metal aa. The point of air is that it can easily move the whole force to a single fight. The ground aa units however are slow and shortranged. So they basically have no chance in hell to cover any ground because they have to spread out and when they spread out they just die to the concentrated air force.
