Changelings should not be able to use the shield of souls

You can still get rid of someone using the shield, it's just a lot harder. If you can somehow eject them into space, their immortality won't help them becasue they'll never get back.

Wrong. I've thrown someone multiple times into space that had SoS and they just used their own dead bodies to get back to station/mining and then back onto station.
