I've spent the whole thread offering a plethora of suggestions as to how someone with troubles could accomplish it easier.

As far as flicking your eyes being "slow", the fight comes to a complete halt for 13+ seconds. So your DPS stops for a few seconds while you get the stuff you need to solve the puzzle. Better than dying, ne?

There are other people in this thread and the community in general who are being kind of nasty to those who are struggling with the mechanic. It's great that you're trying to be helpful, but there's plenty who aren't.
