Tank build: Point Capture ( if specced for healing shouts with soldier runes, using the Fear Me shout). Guardians do this better, IMO, since Fear Me has a long CD even with CD reduction. With a hammer you can play support by locking down enemies and crippling them.
Glass Cannon build: Lockdown and kill. You have 2 very good CC utilities in Bolas and Bull charge. Unload with hundred blades and the spinning axe skill, alternatively you can run condition using a 1 hand sword and shield and watch enemies quickly from bleeds.
