"You better not be peeing behind there!!!"

This story mode or HM? Story yeah..it's a pain...HM though not sure why they call it hard mode...she's actually easier due to it being 8-man which means more bodies can be thrown at the feathers to clear them quicker.

For the story mode, it took me 4 DF tries and around 40 attempts to clear her, I was never sure if it was terrible latency or just people not being able to multi task doing there job and watching to see if she had teleported, but dear god the number of times people were simply unable to dodge the move where you need to run behind a pillar.
The fourth party at least had some stamina and refused to give in, and we eventually ground through it, though it become fairly depressing to be the last one standing over and over and over.

Hope you have better luck.
