Bugs with the sniper (class and weapon) are making the experience frustrating

Playing sniper is proving difficult and is completely ruining the game experience. Please reconsider the sniper class, as BF has always been the best game to play as a sniper, since BF3.

Below are some bugs/situations I encounter every time I play the game, which are making the experience very frustrating.

1. Bug that keeps the aim steady by pressing SHIFT. I can rarely keep the aim steady, making it almost impossible to land a single shot. There are times (very few) when the aim stays steady forever until the shot is fired, but most of the time, the aim doesn't stay steady.
2. Sniper scopes aren't great; long scopes could be made easier.
3. Only maps focused on close range. (Please maintain the original experience with large maps, don't make it a COD)
4. Bullet drop without a pattern; long shots are almost impossible to land because the shot veers sideways without a pattern.
5. Bug in changing keybindings, because when configuring a key that is already in use, it is bound to two functions simultaneously, making it impossible to remove already bound keys.
6. Bug in the map filter; even when selecting matchmaking maps, I am automatically redirected to unselected maps.
7. The brightness of the sniper scope is too exaggerated, losing its logic, as even in shadows, the scope is too bright.
8. Spawn Beacon, an essential for the sniper class, has been removed.

Some points that I, as a fan of the franchise, would like to earnestly request to be considered. Thanks :D
