Hitreg and peakers advantage is still broken

For a short period between patches (sorry cant remember the versions rn) the hitreg was fixed.
Goofballs that would exploit bad hitreg and jump around every corner were suddenly hittable and were getting killed like they should have.

But it seems with the latest patch there has been a regression.

Players you clearly get the drop on can turn and shoot you and win the fight.
Players with less that 10ms ping have poorly aligned hitboxes, or their hitboxes are not swept/interpolated correctly, resulting in hitreg holes.
Some players who jump and slide are no long smoothly animated or can break the timing rules and instantly stand and run.
Rockets and grenade launchers are back to being 'hitscan' weapons, the projectile hits instantly, even at 100m or more.
