A report regarding BF6 from a BF player since 1942 era

I started my FPS life from DOS DOOM, and started my FPS life with BF since 1942. So, I am old as an FPS gamer now.

After playing BF6 for many dozens of hours, here is my feedback. Other people may reported the same, then count me in.

(1). Roof glitches are still flooding.
"Iberian Offensive C building roof" and "Cairo E bridge/tall buidling roof" are being used daily and heavily, making the map unplayable. The solution is simple, you should set roof of any taller building as red zone, easy and fixes everything.

(2). SMGs are overly powered
SMG is surpassing assualt rifles in both CQB and mid range battle, especially KV9 and SCW-10, they are laser guns, overwhelming AK4D or even DMRs easily at mid range. An SMG, beating battle rifle and DMR at mid range, this design itself it's a total failure.

(3). M250 may has a corrupted damage profile
This gun has 25 damage at any range which is not within typical BF damage model.
I doubt this is a bug, not applying the damage modifications.

(4). Visual glitch after saving teammates
For many times, after reviving teammates (by dragging), my visual goes wrong and cannot aim anymore, in the middle of the ADS screen is my hands itself, no guns, no pointer, no aim, just my hands. This is making me hesitating on saving people. Once I was killed due to this and being saved by teammates, this glitch will gone.

(5). Player is running too slow
As a BF player I don't agree with CoD floating teleporting style. But I can feel the character is moving even slower than BF1, which is already being heavy. I spead nearly 3,000 hours on BF1 so I am pretty sure about this ( you can check my profile to verify what I am saying ).
Combined with too quick TTK, this makes SMGs and other high RPM weapons overly deadly, giving people no chance to escape or react.
