So far the only bad experience I have had has been with the mission defend/attack the transport, the design of the mission has only one outcome if you play the mission, if you are defending the transport you will lose unless you find the factory your enemy is spawning at and camp it. If you are attacking the transport as long as you target the transport and NOTHING else you'll win, taking into account the fact that the defender doesn't hunt you down at the factory. It's a very imbalanced mission. The defender will win every time if they camp at the player factory. I'm sorry the mission is called Defend the TRANSPORT, not spawn camp the attacker.
