Difficulty in Finishing Players After Knockdown

It feels harder to finish a player after knocking them down than it is to knock them down in the first place. The main reason seems to be no-reg shots caused by poor server performance. I also know this happens in Apex Legends, where players can even hide behind a knocked teammate, which makes the situation even more frustrating. Respectfully, this mechanic should be looked into for a smoother and fairer experience.
