I understand that we get frustrated with difficulty and Hardmodes, but they are exactly that, Hard modes.
Keep in mind that Rakata pieces drop off the last boss in here, so it shouldnt be easy.
That said, It *IS* a very difficult FP, but not impossible.
I cleared it with my guild the first day and it just required understanding mechanics and working together.
The first boss is definitely the hardest and requires some pretty solid execution, but if you expect to go in there and 1-shot him without learning the mechanics, it's not going to happen. And if you can walk in and defeat bosses without wiping a couple times, then it's clearly not that hard.
If everything was a faceroll and required little to no thought, everybody could do it and the rewards would never be appreciated.
