So I played my current playtrough for a long time and I noticed, that the balancing in the later game just don`t work.

I´m in december and at the moment, alomost zero advent troops show up. instead I almost exclusively encounter archons, muton elites, and gatekkepers, plus reinforcements arrive at almost every turn. Even if I have 200 % infiltration, it changes nothing and the missions are still impossible. One of my regions is being invaed at the moment and I simply cannot keep it. Reinforcements every turn, the sensor to destroy almost 5 turns of complete sprinting away and reinforcements consiting of garekkepers and archons every turn make even a ten man squad have zero chance to get through.

Second thing: is the number of liberated regions somehow limited? I have three regions under control and even if I do every mission in the remaining two, the liberation chain simply doesn´t progress. It only spawns mission with "finding a lead" nothing else.
