Combined with the nerfs to grenades such as no more guaranteed cover destruction, it makes fighting a pain. 2 makes it possible for all enemy types to Dodge, down to the lowest Trooper.Rocket scatter can cause friendly fire to multiple XCOM troopers and is worsened not just by bad Aim stat but also by distance to the target, making rocket use even more of a gamble than in vanilla. It's bad enough when normal guns miss, but at least they don't do anything then.
LONG WAR WAR OF THE CHOSEN MOD
Several meta-mods have been made to reduce the penalty for low infiltration so players can actually make use of their combat power, and eventually the mod itself changed things so bringing only one soldier doesn't make that much difference to infiltration as bringing three or four.
Others, on the other hand, consider it a problem since the mod gives players all these fancy new classes and a bigger maximum squad size and then penalises them for wanting to go to town on the aliens.
