I already soloed her a couple of days ago, but missed to fraps it. On that first kill, the fight took about 10 minutes ... most of the time was spent with kiting the adds in P2 and trying to stay alive. The next days I tried to down her with an alt (which is also a mage), but on my best attempt I could only bring her down to 25%.
The additional practice apparently paid off ... after the ID-reset, I've been able to rekill her on my main without too much of a problem.
