Limb modifiers are an interesting change but there are cases where it will make combat way more unpredictable

And anyone who ever sniped before already can guess the main case (however this will also occur in normal close range gunfights).

Namely - when people hold guns, they usually hold them in front of themselves, covering upper torso (or depending on angle/animation - their head). So now the area which is usually your go-to default to deal not the most but most reliable damage is largely covered by a limb that used to have same 1x modifier as rest of the torso and now it will actually have an even lower modifier.

This already is apparent when sniping in cases where even if you only see the head of your opponent and yet somehow still score an 80 shot because when two of you are facing each other, somehow enemy hands catch the bullet instead of their head.

Those cases will now be even worse and regardless of range, damage output in face to face combat will be very unpredictable.

Counter strike already ran into this issue years ago and they solved it by double checking whether the shot that hit the arms, did not hit anything "more valuable" along the way and in such case, counting the hit against that hitbox instead.

Limb modifiers are fine with the intent to reward careful aiming, however the design intent likely was to have the modifiers apply when you deliberately target the arms (like someones hands sticking out around the corner) and not making direct gunfights output vary on bullet to bullet basis because some of them during a head-on encounter did hit an impenetrable shield of other players hand.

Just my two cents as i predict people will start noticing this after the update.
