Agreed, also with how the Devs seem to have done the majority of the "bosses" in this part of the arc I can only imagine they continued that pattern throughout the entire arc. While this end boss is difficult, it could teach the strategies and techniques to defeat the harder bosses in the next part of the arc. Kind of laying the ground work and getting folks used to working as a team so they stand a chance at taking on what is to come. *shrugs*... never know....
I am also holding out hope not all of the drops have been uncovered. I am still hoping for a deco drop from the dude too, although that is getting to be a slim possibility.
