Hey, good one, Soul! I agree Kalifa's Awa Awa no Mi could have been a logia, if Oda choose to do so in an alternative universe.

You're right. I can see your point in Kuzan's ice DF being actually something solid, unlike Monet's snow DF, but yet is branded as a logia.

About Brook, I have a different idea. I picture the hypnotism powers of ye old bones to be somewhat related to him controlling the sub-conscious souls (rather than mind) of fodders, a skill more refined after the TS. Therefore in my own opinion, I attribute it, directly or indirectly, to his DF powers. I may be wrong but that's what I think.

Going by this line of thought, I would think later he will develop a way to cut into a person's soul (with physical body unharmed) or perhaps cut into opponent's confidence (somewhat tying to the soul kinda stuff) in the future as part of his power / battle improvement.
