Is the fight a challenge? At first yes..

You will probably lose your first few times before you win, but that does not make it "hard" and "unbeatable"

Like any encounter you have to learn and adapt to what works.

The problem lies in that one group finds a way to beat it, and everyone copies that group and then you get "you have to have sent", or "lancer only" etc, etc

It you experiment and can handle giving the encounter a few tries before you come here and qq you will be surprised on how easy the fight really is.

We have beat it with 1 lancer only, have beat it with a lancer tanking, have beat it when our tank DC's, have beat it with 1 mage, have beat it with 2 people DC'ing, 7 people total..

The only hard part of the fight is the loot system..
