I tried to PUG Dhorme Chimera with some folks last night and we wiped like 7 times before the party leader (who died first every time) disbanded the group.

An all FC group formed later on when we had enough on and took it down in two tries with no deaths on the second attempt.

I think the game is already plenty challenging, especially at 50. I don't know if it's a wise business model to put things further out of reach of people. That's a good way to lose subscriptions. I'm not saying they need to nerf things (although they've said they will once said content is no longer cutting edge) but I don't think they need to be made any harder.
