I'm in the Storm King + Flim Flam boat. I just honestly feel their not... the best at being villains. Flim and Flam just annoy me, 'Give us your bits' aren't my favorite type of antagonists. The Storm King had Tempest do all of his work, and that's really just lazy. If your gonna be bad, and use teamwork, DON'T just have the other one do all the hard stuff.
That's just my opinion though.
