Odd yes. But more intieresting then most other systems of magic out there.

I'd also like to point out that while they can't swim, they're almost all pirates on ships on the water. Their logic is flawed.

No, that is an intersting point. Would you trade your ablity to swim, potentially causing you to drown, for some kind of power that could be awesome or useless? That question is brought up multiple times.

Besides, try pushing a guy made of fire in the water. Or a guy who can put up barriers.
