I also haven't really notice a huge change in the AR/SMG, AR especially. It still shreds especially if you get the first couple of bullets on the enemy. Smart Scoping with the AR especially still has really good range.
AR: This still feels like it can destroy too easily. a slow tap-fire (release every 4 or 5 bullets) keeps the spread under control and still extends the range significantly.
I really disagree with this: Firstly, the fact that 4-5 round bursts extends the range and that it does better if you get the first shots off on the enemy is the entire point of the gun: It's an automatic weapon that is capable of enaging at medium-close or even medium range if you use accurate bursts, and is especially good at getting kills on enemies you have the drop on, that's why there's a silencer on it.
You guys just seem to want it to only be good up close, which is what the SMG exists for.
All of that being said, The AR isn't even worth using right now. Before, full auto spraying was absolutely too good, to the point where you were better off spraying then using accurate bursts, but now even though you need to use bursts to use it past point blank range, it's not even worth it due to how low the DPS is relative to the BR even at closer ranges. It's still better then the BR/Magnum at point blank range, but then you don't need to burst anyways, so there goes trying to reward skill with it, which is what the point of it's changes were; and at that range you are better off with an SMG anyways.
Right now the AR is stuck at a place where the SMG is better then it up close and the BR is better then it at medium range, and it's not good enough at the distances in between relative to either of them to be worth picking up relative to sticking with the BR or picking up the SMG instead.
Close Range - fighting up close with this weapon feels artificially difficult. Cant tell if its the aiming, the Aim Assist changes or a combination.
TLDR; The problem with the BR was that it would aim for you and bend bullets around corners. Those issues have been resolved, but then a bunch of other unnecessary -Yoink- was done on top of that. KISS.
This is a good thing, as is, the BR is still too good up close relative to the AR.
