Warrior rouge can easily own everyone with a really good set and good weps (especially dagger). It's a good char if you are skilled pvper with it, and you have no lag (it kills you if you are delayed when you have to change weps).
If these are ok, warrior/rouge is one of the best pvp chars.
Only enemy is a rouge/warlock (if the player is fast and skilled), but they have more weak points than warriors, because warrior can kb/kd/sprint at the enemy, which can save its life.
EDIT: If you prefer chinese, try a dual wep char, bow and glavie also with a really good set and weps. Necessary, or you get killed easily, though when you attack with bow you have advantage, because of the hp buff of heuksal skill tree.
Once I pvped with a char like this, he had better set than I had, and couldn't kill it with a warrior rouge, even without lag.
