Overload weapons no longer apply exhaust or stop abilities. This also applies to the Overload Grenades perk despite it stating otherwise. Barrier weapons no longer penetrate through enemies. This decreases the player's ability to apply and base a gameplan on exhaust, and it decreases the effectiveness of some weapons that used to benefit from these effects greatly, like Revision Zero no longer being able to hit multiple enemies in one sniper shot. Since text in the game still references these effects, and there was no mention in recent articles of them being removed, the expectation is that these effects should still exist.
