Ah yes, that is a point. But still, it's no slouch in the Devil Fruit power department. Since it basically gives the user complete spatial control of an area around them, which is basically an "I win" button in an RP.

I agree. It does have its limitations, like its relatively short range and the fact it tires out the user, but it just has too many complications to really use in an RP. Things like cutting someone into pieces or swapping their souls around could be fun, but it's the sort of thing you really need another players permission to do to a character and it wouldn't happen too often; you'd be limiting yourself most of the time in what you can do.
