this is my OT/RF build..you can use the remaining SP for the skill that you want..
-wild charge is awesome! but in some servers, it's not available yet (HK, TW, GER)
-arc enemy is good for PVP, more damage in combo (with skill note, it will reset the KD counter and will hit twice)
-charge bolt is good for PVP as well especially when there's an enemy on top of you (with skill note, it will increase the size by 30%)
-if you have a B slot, you can choose guardian strike for AoE
OT/RF will rely on combos in PVP..x crash and weapon break will be used often..ground impact as is good for combo as well..
