I think a lot of people have totally missed the point of this... it is not MEANT to have much of a reward and it is not MEANT to be completed. This is meant to be the Absolute Virtue of FFXIV; a boss that is supposedly undefeatable giving the most elite of the elite a chance to prove the developers wrong.

If you need a reward to do it then you are not the intended audience, if you don't like challenging content then you are also not the intended audience. This is quite literally ONLY for the people that cleared the Second Coil in those first few weeks and are getting bored of it. Considering that this is the untuned version of the raid it actually will take very little development time to implement as all the work has already been done; all they need to do is add it to the minstrel in Rev Toll and have it unlock as a new Minstrel's Ballad.

For the record I will likely never even attempt this but I appreciate that there are some that will enjoy the challenge.
