Even in a 1 on 1 there are much better builds for swordsman in PvP.
C passive blocks helps you only against physical classes and you can nothing do in the time you use it. I am unsure if this will help you much in a 1 vs 1.
25 % extra hp is not a heal so you have to use it before the 1 vs 1 and heal up in advance.
You have only 3 CC skills in this build with Bash, Umbo Blow and Mordschlag.
All have a bad animation time for pvp in my opinion.
Two of this are only knockdowns that push the enemy away from you and the other one is not even a reliable stun.
How do you expect to deal any damage with cyclone ?
You slow as a turtle and can’t hold the enemy in place.
Everybody can simply run away from you,
Spear Throw makes it really hard to hit moving targets.
Finestra and Long Stride are fine for PvP.
And Dragoon skills are good for PvP without question.
But there are much better choices then hop 3> dop in PvP.
Cataphract 3 gives you CC, movement speed and bonus life.
Corsair gives you rang CC with Iron Hook.
Swordsman 3 gives you longer Pain Barrier and Restrain.
Rodelero gives CC and magic immunity for some time.
