Display MoreHmm if you starting from the bottom you should first go into the PvE, Dark warriors are beasts of farming, so you can get good gear to do PvP. Anyways, here is a good guide to start with: Dark Warrior Guide
Links from builds are down but I made one, pretty standard but useful for what you are looking. PvP Build
Also, you are lvl 47 so you are at your weakest stage, you dont have enough SP's yet, and you are missing your best skills.
And this, is a build for the current lvl cap. Lv60 Cap
''Charging Fist'' is to KD.
Demon Wave can be a good skill, you try it.
Hellzone Grenade doesnt do much dmg by maxing it.
You try yourself different skills and builds, remove what you dont use and max what you use the most.
Special Beam Cannon is the strongest skill but takes a lot of SPs for this cap and even at 70 cap its not easy to use, but really powerful.
Good luck
Thanks for all the help once I reach level 50 I'll start worrying about my build.
