@audiofilomx As you said in your comment: "high level players don't land 11-8 shots", I strongly believe that it's a player that defines a weapon and a weapons might not be OP for everyone.
Even in your shared clip in your very first comment here, we can see you land 3 PK shots (out of 4 shots) on Watson and she couldn't hit you with a Havoc rifle and you use that as an evidence for OP PK... but honestly, he was a bad player and you played well, it wasn't a weapon.
While many asked for Havoc nerf right now, one can use the same clip to say Havoc is weak, but it is not the weapon... it's player and playing style.
Taking down someone with 4 PK shots out of 5, is exactly equal to using 24 flatline bullets out of 30 for taking down one player.
(Quick math: flatline does 19 body damage per bullet, so just 24 bullets will be 456 damage, which is actually enough to down 2 players with purple, is this OP too?)
