Atleast the deep dungeon is good.

I will admit that it was fun and engaging. Seriously, it was great, but the lack of rewards we can purchase with those fragments really left me doing a double take. Checked the vendor once before heading in, was confused and thought "This can't be right. Oh well, maybe they unlock after floor 30 completion." Did that, went back to the vendor and there was still basically nothing aside from a frame kit (Yay....). Checked it again right after that because my brain couldn't process what it was seeing. Left disappointed.
