Guild Wars 2

I have done approximately 20 runs of this dungeon, some lasting over two hours.
Every single night for the past week I have been in this thing. I did FTL without issue, and I eventually got Personal Space.

But no matter what I try, I cannot for the life of me get Unfriendly Skies. Even if a group obliterates the first boss and the trash, it just falls apart incredibly quickly when we hit that final boss.

And so, I’m asking for help. I don’t know exactly what I can offer, so all I’m going to do is ask.

Is anyone willing to help me with this?

By that, I don’t mean attempt it once, wipe on the first barrage and then quit. I mean spend as long as it takes until I get this kitten achievement. Up until now, I have every single limited time content achievement, but time is very, VERY quickly running out for me on this one.

If someone was to help me, I would give you my eternal gratitude.
I’m up for runs for the next 4 hours or so tonight, and every day this week from about 10am to 11pm

I’m totally out of ideas.
Thank you
