I've been enjoying the main story quests so far...until I came to this one. I've hit a wall. Okay so it's a big battle, cool. One of the objectives is to protect a certain npc in addition to killing the enemies.

Problem is, I'm a Pugilist.
What exactly do they expect me to do? Grab the npc's aggro and pull the mobs off of him? I couldn't if I wanted to. Heal him? I'm a DPS class, I can't heal and I can't kill them all before this guy dies, always happens 2/3 of the way in. How can I possibly be expected to protect this npc? I've a veteran to the MMO genre as a whole and I love a good challenge but I simply can't do this, It's not what my class is designed for, how did any of you non-tanking non-healing characters tackle this quest?

I even took 10 levels in Conjurer so I could cast Cure I on my Pugilist, but those dinky heals don't make any difference in the Duty, he still winds up dying.
Any help is appreciated
