if ur not using ur fists then don't master tka, go 4 0 0 0 or 4 0 0 4 then take up dirty fighting of smuggler for FD and low blow/last ditch etc.. then master pistoleer and take up flame thrower line of commando if your going to pvp. no reason to master smuggler or tka, but pistoleer is worth mastering for these type of templates.
