First, invading a planet shouldn't be about taking out an orbital gun, it should be about capturing territory. That being the case ditch the stupid destroy generator objectives.
Then just make the attack about driving the enemy off the planet or destroying them utterly. Why? because this is what attackers do to win an objective. Simple logic really.
Then you give the defender only 3 waves or 36 mechs against the attacker having 4 waves or 48 mechs. Then if necessary you beef up the defensive positions with more or stronger turrets, maybe toss in a mine field or two and make the orbital gun, a fort where the enemy can fall back on it and hold it till the last man.
Then to add some spice to the game. Make the generators control the turret defenses and minefields so that taking one out, neutralizes a entire section of the defenses, including the man generator at the cannon neutralizing the fort area defenses.
Generator Destruction Incentive, 25k bonus C-bills to everyone on the attacking team per generator destroyed.
Winning conditions:
Attacker: Destroy all enemy mechs
Defender: Destroy all enemy mechs or hold out until timer expires.
Simple, fun, insures everyone is getting a good battle, no gimicky tactics required to win and probably more importantly requires very little modification on PGIs part to make happen. Hell they could probably throw this modification to the system into place in a week.
