Honestly, this fight was both amazing and miserable at the same time. I don't think a MSQ boss should be this difficult, and I can see where a lot of people may end up getting stuck at this part if their parties can't get it done so it probably should be nerfed simply because you have to do it in order to finish the MSQ. It only took me 3 tries, and when I got it done it was only barely. The second phase is an absolute nightmare, and it's very difficult to make heads or tails of what's going on there. There are hard/extreme modes of things for a reason, I don't think I will ever even bother with this fight on a higher difficulty.
