For me personally, im 100% brawler....
Master Brawler, Teras Kasi Master, Master Pikeman, Enhanced Reflexes Master, Combat Prowess 0/0/4/4.
Dont know about the best PvP template but i got some evil weapons available(dots) and i dont think any 1 or anything can match a tk masters speed. My defense is also pretty damn hot.
I cant really say for sure that this is the best as i havnt quite finished the FS, but so far so good :)
