I don't see any one man army supporter Location swap is just a lesser teleportation skill. He can just get real teleportation later. The only help it can really be is if he uses it to help comprehend the laws space and space magic. Of course it can be used in life saving situations but how many life threatening situations will he be in. If I'm thinking wrong and it's op and allows you to swap places when teleportation is restricted and steal someone else's item without them being able to do anything to protect it then I will change my stance. Until then one man army seems the best unless it's just a skill that's easy to obtain.
