How are you doing last boss? I've had zero problems with the whole instance, except for the last boss. Either the group is thrown around, or one toon is gripped and slammed into a vortex, or the adds swarm my team.

How long are you spending on the fight? Where do you setup to pull? Do you try to position the blue vortex things to take out adds?

Any help would be awesome. I'm stuck on the last boss, running a mixed team with no melee.
