I have had the same experience from a bunch of "pro" players for the Crotas end raid. (Americans though) they were all friends. I didn't know what i was doing but one of THEM would die everytime. after we failed five times on the last part, I got a message saying I was "-blam!-ing terrible" me thinks one of them was saying it was me that kept activating the oversoul :/ (before change) so I looked up how to solo it. solo'd it, and sent them a msg. :p
