Sniper rifles need balancing !
1- "Sniper glint"
The glint glow is too noticeable, the glint should remain but the glow strength should be reduced.
2 - "Bullet trail"
Sniper scopes already have big glint. It already adds a huge disadvantage. Sniper bullet trail should be removed. Also, it looks very bad visually. Either scope glint or bullet trail should be selected and the other removed from the game.
3- "Sweet Spot Mechanic"
"Sweet spot" is a useless mechanic. There's no way to tell if an enemy is within range. That's why you're trying to hit them headshot at every distance. Instead of sweet spot, you need a one-hit kill from the torso at close range, like 0-50m. So, it should be like BF3-BF4.
TTK in the game is incredibly fast. All assault, smg, lmg weapons in the game kill in 4 hits from close range, some full auto weapons kill in 3 hits. And assault carry two weapons second shotgun 1 shot kill. Snipers cannot single-shot body kill and in this situation it is impossible to fight them. Sniper weapons should fire single shot kill from the body from a distance of 0-50m. If this is not fixed, recon will remain a dead class like in bf 2042, no one will prefer it. For a fair fight, it should kill with a single hit to the body at close range like BF3-BF4.
Additionally, sweet spot mechanic that forces players to camping from a distance. If instead it's a single close-range shot to the torso, no one camps, everyone plays in the combat.
