I did not have fun with the fight as summoner. She kept wanting to attack me all the time and I kept dying all the time. I felt bad for the DF group I was with.

Then later I tried it again as a WAR and finally finished it. But one thing I noticed was that if I didn't get enough hate right away, she would always make her way towards attacking our WHM, and always the WHM first, even if no one else was doing anything. Not sure if she likes going after mages, or just people with lower HP.
