It's a lot faster if you kill the Captains. 2 per Captain, guaranteed. Two Warriors practicing the ancient, almost lost art of bandy cross healing, can stomp the Captains, especially if they're using Weapon Masteries. Onslaught works great against Captains with 0 Resists but high Health, while Stagger and Pierce work great against hard hitting Captains such as Macers or Fencers, greatly slowing down their attack speed and making them less dangerous.
I usually do Blackthorns Captains on my Macer/Pally. Between Hit Fatigue on my wep dropping their Stam to 0%, and Stagger giving them a -60% SSI debuff, i'm pretty much never in danger of dying against the Captains once they run out of Stamina.
