After failing hard again and again as power-specced ranger, and reading that being full zerker is the only way to go, I decided to to try something compeltely different. And it worked perfectly. I worked so great that I have a suspicion that it might be the most efficient way to beat her, better even than full zerker shortbow.
Credit goes to user Vatlaaw Fierceshot, whose slightly modified build I used to beat her.

As for the build, here it goes:

I used speed booster to compensate for the lack of Signet of the Hunt. As for food, you can use any +condi duration and +condi damage one, I used Koi Cakes, since they are pretty cheap nowadays, and Tuning Crystals.
I used runes of undead. They are cheap, and suit this build perfectly. As for sigils, you can use anything you want. I used Superior Sigil of Smoldering, because they were cheap and I was running out of money. (I am broke, I confess). You don’t have to spend fortune on all exotic gear. I had rare weapons/trinkers + exotic armor, but it should be doable just fine in full rares.
As for strategy, the phase 1 is pretty standard. Destroy the first rift as soon as it spawns using sword (be carefull not to press the AA twice, or you’ll end up flying all over the place), use Axe 4 to pull Visions of the Mortality to the vortex to get the crystal of light (sp?). After throwing second crystal at her, be careful as second rift spawns.
For phase 2, swtich to Axe/Torch. This is actually much more simple than with zerker shortbow build. As soon as she stops being invulnerable, pop Rampage as One and use Torch 4 to apply burning on her. Now you can fully focus on dodging the AoEs. When you get crippled or your health goes too low, use Healing Spring to heal and cure conditions from you. From time to time, use torch 4, 5 or Fire trap to re-apply the burning on her. Make sure there is burning on her all the time, or you risk running out of time. However, I found that unless you make too many mistakes in phase 1, you have more than enough time to beat her.
Hopefully this should help those who still have problems beating her. As always, feedback is welcomed, as I imagine there are better options in some parts of the build.
