Aurum Vale, Coincounter questions.

Just ran out of time after killing CC, wiping around 6 times.

Went through a couple of DPS who left before we got him down.

Eye of the Beholder, are you safe directly behind him? Is this a decent place for a healer to stand? I noticed once during the fight our healer took no damage, and also in a video on YouTube and Archer takes no damage, but she was pretty far away from him. Not sure which resulted in her not taking damage.

Does he ever fully resist stun? Stunned about 3 100-tonze swings, never got to a fourth. Wondering if that's a viable strat for avoiding it/saving people?

Eye of the beholder is a huge cone in front of him, I think it's like 160 degree arc or something, distance is pretty far as well. You can move behind him for it or be really far away from it. He can be stunned, my friend who plays MNK stunned the 100 tonne swing move.

I usually do that as such:
ranged stack near CCs buttocks, tank runs through him on swipes, runs back.
ranged get targeted by glimmer, sidestep to avoid.
repeat until eye, where everyone stops everything they are doing and runs behind CC.
repeat, stun swing, win.
