You ideally want a good reach weapon, Never Outnumbered skill trick, and the Imperious Command feat. I like combining Intimidating Strike with that, others might not. Doing a Barbarian build with Instaneous Rage or Ferocity variant Rage and the Intimidating Rage feat is great to add to that, too.
For healing, being a draconic character and getting the draconic vigor aura as a feat means everyone around you gets fast healing constantly, up to half max hp. I don't even think you need to be draconic, being draconic just increases the fast healing amount above 1.
