Conclusion of the update:

One step forward, two steps back.

Problems remaining:

1. Bullet registration is really bad again. So the history path according to the fixes is: bad, better, bad.
2. Instant kills. The moment I see the enemy, the same moment I die. No chance even to click the left button on the mouse.
3. I shot the enemy in the face twice with a shotgun, 1 meter distance. No damage, obviously I died and I didn't even saw the mark of my hit.
4. Vehicles do not have the same engagement/impact in the game as in previous versions. Many vehicles, many mines that can't kill a tank. I see in city maps the roads full of dots of mines like PacMan. The most impressive thing is when the aircraft or damaged tanks land next to the soldier, but after a while you feel like this is staged and the vehicle doesn't seem to be part of the action.
5. In every game and every map, a tank dies only with rockets. Mines and C4 are no longer useful. Other vehicle equipment that is not used and does not offer any exciting experience. Only guys who camp near the base and wait the whole game just to manage to kill a tank once or twice. I guess they do this just to unlock something.
6. Helicopters seem to be the most inconsequential object in the game. And while helicopters don't tie into the overall gameplay, you get a direct hit from a helicopter hovering (camping) so high in the sky, completely unrelated to the action.
7. In BF3 and BF4 I had so many equipment choices to use, to adapt to the game and influence its outcome. Now the most of the gadget choices are not useful and do not affect the game.

I told you before. This game has so many problems that you can't fix them.

If you have the courage you can try to fix it. If I was in your position I wouldn't.
