Personally, I don't mind players calling each other on rules interpretations which make each other uncomfortable.  I'm sorry I haven't been around, but I've had social duties to do.  Anyway, Djinn can't cast wind walk normally, except via a wish.  If you'd like to dispute that you can go play a different game.<br/><br/>I consider it unbalancing for djinni to be able to cast the equivelent of a 7th level cleric spell, since I'd prefer to balance their abilities at about 5th level.  (with the exception of their wish ability, which is in the realm of plot device.)  Djinni are supposed to be the equivelent of demigods in setting, but they can't control their power efficiently, and most of it is tied up maintaining the elemental planes.  What this means is that their elemental powers don't tend to be that much stronger than that of other elementals, though they have other magics to make up for it.
