Remove genetic things from lings entirely.

If they are able to consume and use human DNA, why would they not be able to use human genes and the traits they cause? Like...what? That logic doesn't work out, friend.

As for making them "functionally any different", they can't use their PDA to order in traitor items. Their traitor items are their stings and toxin spits and shapeshifting. They also have a very different objective if you're trying to "win".

This is a bad idea, friend. Just let it go.
