For T9 here are something's to consider:
1) the DPS check starts at the very beginning of the fight. Never stop hitting the boss... Ever.
2) save SSD for the first iron chariot. If you did your rotation right, you'll land an ID drive right as she jumps for iron chariot. You then have time to SSD over to her, throw up the CT, run to middle. Once she turns to face group you can run out to pop HT and phleb as she lands back on tank
3) also watch out for exploding tank. The tank will explode a few seconds after a skill she uses I forget which, if you use jump during explosion it triggers as you being in aoe and will one shot you.
The rest is all preference and how your group decide to do the mechanics. We solo tank it and only get one add on heavens fall and four meteors (very close to pushing three meteors![]()
