This is my way to build up a Brawler. Keep in mind, that I only tested it in PvE, so far, and its in Envoy's path. Anyway, I recommend putting your envoy's path points into high crit rate + crit damage, and the Secret Techniques buff. This will help you cause a lot of damage, and get tons of crits. And, with the secret techniques buff ( which activates everytime u land a crit ), you can inflict even more damage. Also, it doesn't hurt to add some, or a lot, of evasion, in Envoy's Path, as well. As for how I'm building stats, I'm keeping mine balanced, but how you build up in stats, is up to you. This is good for gunslinger as subclass.
