not to sound negative but I have had decent luck clearing it with the duty finder. its not terribly hard if you simply go in and learn what to do, yes people drop the party and you get a new person but its step by step and when you are comfortable enough put together a party finder to clear it.. on top of that next major patch an even higher item level will be here (probably 130+) which will not only increase players survivability but their output. So on top of the echo you will probably have an additional 10~15% HP on top of the echo (which I believe is sitting at 25% right now). I really dont see what you want them to do? Are you after just walking in and the boss killing itself? As far as coil 2 goes... I have done coil 2 one time, my first and only time I went as a WHM and I did T6-8 and learned a bit of T9. I will probably eventually try to do it some more but I am not sure yet as I dont consider myself a raider.
