Before this thread becomes even more of a shitstorm than it already is; I’ll give my few words (though, it’ll probably be twisted backward), also, this is from someone who has not yet been into the PvP/GvG scene so feel free to disregard this.
From all the threads I’ve read on about the Swordsman class within the PvP/GvG environment, one thing is clear; Swordsman are outclassed/inferior to other classes. Some specific builds for Swordsman can work in PvP (typical Catagoon, Corsair, etc) but they’re few and far between compared to the rest of the classes; there isn’t that much variety there.
One of the reasons a lot of Swordsmans don’t do well in PvP as Mirarara suggested may simply come down to expectation. Swordsmans, in most games, are the frontline powerhouse; they do physical damage and take damage better than any other class, typically, but that’s far from the case in this game. They have some of the worst DPS and not nearly as much survivability as expected from the traditional Swordsman role, so they’re religated to a pseudo-support unless they are one of the better PvP options. As far as I know, no one picks up Swordsman to be pseudo-support, so people don’t expect them to so underwhelming in where they would normally excel in and it would take both time and creativity for people to adjust to how Swordsmans work here.
Besides that; other classes just have it both better and easier whether it’s from better damage scaling, only needing to invest in one stat, or just having an over-all better toolkit. Swordsmans (specific classes) can and will work in PvP/GvG but there’s just no denying that they are lacking compared to the other classes and, at least, some buffs would be appreciated to close the gap.
