Who paid you to grab Dr. Pavel?
If you think it was game design decision, and they included ADS as way to balance the guns, you are sorely mistaken (what a stupid way to balance them that would be BTW)
ADS is there not to scare away the modern shooter crowd, and to avoid some stupid reviewers saying "no ADS in 2015? LOL" That's all there is to it.
But they did balance it that way. Just look at how much more you can see with the BR zoom. It was clearly taken into consideration.
