Basically, after we killed the first frozen orb, my guys all got stuck targeting it, even though there was a [nodead] modifier. Dunno why this happened.

So we just manually assisted. And here is what we decided on next time, since we know you can taunt the orbs now.

Basically I play my five guys, and he plays his five guys. We have 2 healers, and each just focuses their respective tanks, and does their aoe heals on cooldowns to negate incidental damage/whiteouts.

We will switch tanks at 4 stacks of frostbite. Whichever tank is NOT tanking currently, will target the frozen orb, and taunt it - not tank it, just taunt it so it starts running toward the tank. He will target it, and his team will kill it. They only have 130k hps so they usually die before they even reach the tank. Basically I would suggest doing it this way.

And if you were ten boxing, to simply pay attention to your two tanks, and have half of your guys assist one tank, and half the other. One healer per tank, and also does aoe heals to keep everyone topped off. One tank is always tanking, and the other when an orb pops taunts it towards him, and the three dps assisting him target it and kill it.
