To start out with build warfare up in onslaught. when that is maxed build defense up to quick recovery and take 3 pts. Then use quick recovery in emergencies. Now take batter/rend and use that for AOE attack. Now role up defense and get the shield proc skills: disable/pulverize/etc. Get weapon training. Get Defensive awareness in order to get its shield synergy and take 1 pt in iron will when you need stun resist (get the rest from +skills and gear).
Intermediate: see how that is going. If you get + skills then start putting 1 pt in all the skills I list and climbing warfare. If not just pick and choose what you need.
Advanced: you'll become the expert! And you'll tell me whats wrong with my build because you'll find better.
Edit: a good trick is to watch when adrenaline triggers. Then blow rally. You get lots of health.
