it’s not projectile velocity issue, it’s a flight issue as Malogos mentioned.
Malogos played back when we had 2000-2600 m/s projectiles and we did not have this problem for years. You have a ship evasion issue due to the high amount of drift and the the fact that the ships can’t clear the nose of the other ship.
If there is anything wrong with projectiles it’s the fact that the lifetimes are way too high and that there is not enough spread.
Go deeper with the explanation then.
