you are confusing something
strafe never granted attack rating, it was added as a new thing in 2.4
you probably are referring to other ranged skills not granting attack rating? i have tested that too, there is no such bug in D2R
it does not, i have verified it - https://www.youtube.com/watch?v=MiEP-eEFefU&t=3s
you can see the attack rating numbers
no pts in penetrate but it doesn’t even mattter
