Attacks:
Whirlwind - immune to stun while Whirlwinding, otherwise vulnerable. (Much like the gurubashi Axethrowers in ZG)
No aggro list -- It clears every whirlwind however note if you are a Warlock and spam add up with a bunch of DoTs the add will come kill you.
Enrage - At 20% she will go enraged, buffing her attack either a little or a lot. During this fight, you have to get her health below 30% within ten minutes, otherwise you will get the hard version of enrage, which is near impossible to win against. If you do manage to get her under 30% within ten minutes, you'll get the easy version, which is roughly 10x less powerful.
Strategy:
Neither Sartura nor her mobs have an aggro list, they go around attacking whatever they please, much like Lava Annihilators in the Molten Core. They have a devestating whirlwind attack cleave-like, which if they are near too many people will destroy your raid. After a whirlwind aggro is reset.
DO NOT USE DOTS - they will get you killed! Cloth and Leather wearers are the most vulnerable in this fight. Remember to spread out sufficiently or you will find many die quickly.
Each add will be asigned a warrior and a druid, too keep them in place using taunts, once add dies druid goes back to healer mode and warrior moves to help taunttank sature.
When her three guards are down, you can get closer to attack her, but try and stay as spread out as possible, because if she whirlwinds your raid will get decimated if your too close together. You want to get her below 30% from the time this fight starts, otherwise she will have an extremely powerful enrage when you get her to 20% and she will be impossible to deal with. At enrage it is important to stun her whenever she is not whirlwinding, this will lower her DPS alot. Go all out when she enrages
