Keep in mind that restrain is completely countered by PD’s bloodletting, so that’s why you barely see any in the top 50, especially those using restrain.
Is swordsman bad at pvp? Not really, rather there are certain classes that are just pure hard counters and classes like PD that need a nerf.
In a good team, where your with a PD, you actually can perform really well depending on your build.
