Here's how I do it...
There is a circle on the ground around the boss... several actually. Simply step back to the first circle (roughly 15 yard radius, this circle is far enough away to not take damage from the tornadoes) during that phase. Don't get hit by the tornadoes as they do debuff your speed and it is a little more annoying to heal now if people are spread out and you have a debuff. Just ignore the adds. If melee wants to go deactivate them since during that phase they can't do sqaut go ahead but the adds don't make a big difference on the fight regardless.
So in summary, this fight now has been upgraded from:
You put your right foot in, and keep it in.
You put your right foot in.
You put your right foot out.
You put your right foot in and you shake it all about.
You do the hokey pokey and you collect your easy loot.
That's what its all about.
