I agree with gavin overall, though maybe not for the finer details. The mechanic for revealing alien positions was often too dangerous, thus resulting in an injured veteran team member. So now you either play the next mission with a handicap(rookie) or you save scum to prevent your experienced member from getting shot.
Kinda silly to reward the player for completing a mission by making them less powerful for the next one. You can have backups(which still requires playing at least some missions at a handicap), but fuck their tedious UI for switching loadouts every mission.
Of course, the third option is to turtle up and hope the aliens meander into your overwatch crossfire, but that's more boring than save scumming.
