I rarely solo on my captain, I made the decision early on in RoR that Captain DPS was not what it was in Isengard. As a result I specialised in tact mit, vitality and busting out the hardest heals I could. Means I'm really annoying to take down so creeps don't often bother, leaving me to heal/buff my buddies while restoring power and poking my enemies with debuffs. But then again if 3 creeps come at me in this build I can usually take them down if they don't get away
just takes a while ^^
