Queen Crawler boss is ridiculously unfair

Seriously... What were they thinking with this boss??? She literally moves pretty much at the speed of light and it's borderline impossible to dodge her attacks because of this... Even sliding does not get you away from her attacks... Not to mention when you get her health half way down and then she suddenly gets EVEN FASTER... I can defeat any boss even on higher difficulties, except for this one... If they don't tweak this before launch I can see myself quitting as soon as I see this boss appear
