I want to pug this on 10 man so I am trying to understand this as good as possible as I will have to explain this fight to others.
First of all I hope my Naxx25 gear is decent enough. Other than that I have trouble understanding the 2nd phase a little.
I understand that there are 2 debuffs and that you need to get hit by the other debuff to negate your own debuff. When you start to DPS Acidmaw (he's on the ground first I think) the tank and randomly hit people get the slowing debuff and they have to run to the Dreadscale tank to lose the debuff.
What does the Acidmaw tank do? He has to get rid of the debuff doesn't he? He has to get out of the poison clouds.
When the mobs switch, do the tanks stay on their previous mob, or do those switch as well?
