I thought they removed incremental damage on the strafe, since now a single gren squad looses 1-2 guys, and when there are multiple they each loose around the same number each, because from what I remember a single squad would get insta killed, while multiple squads hardly took damage.
An innate part of how Strafe worked was that the fewer targets were available, the more shots they took. By turning all Strafe's damage into incremental accuracy, we basically invert that behavior. If there are no other targets around to share the damage, you won't be hit.
Basically as squad members die, the damage Strafe does drops off exponentially so the whole squad will almost never be wiped. Unless you're on top of another squad anyway.
