No RoJ warrior, please. Trying to use a melee character as a caster never works well. Your job is to take out casters who are attacking quarries. If your build is suitable, then kill turtles or guards.
There are several useful builds on pvxwiki for warriors in PvP. As a starting point they do very well.
http://pvx.wikia.com/wiki/Main_Page Try them out and see which ones work best for you. When you notice you have a skill that is under-utilized, replace it with something else, perhaps from a seconday line. This is how new builds are created that fit your play style.
