Try better aim 2.0 or some mod that increases your soldier's aim like that. Try playing without the increase to enemy pod size. The aim of the collection is to make every mission a hell of a firefight in uneven odds, having better aim than the enemies is nothing bad.

This needs more XCom buffs. Holy shit I just tried a mission and got annihilated. Even with six people, with all the pods active and reinforcements bringing in 5-6 people, some with armor its fucking insane.
