But this is wrong though. Ok I will agree with you for a minute. So what I will do now, is join my HT with a Tyrant guard. Since now he is an IC he will leave the TG and join a brood of Carnis or a brood of 30 termagaunts. You are making him out to be an IC, so there for once he joins TG, he becomes an IC.
If we go that the HT can be picked out in CC like a IC, then he can leave and join another brood then. It's only fair.
You are making a rule that benifits you without any proof. So by going by your logic, it's only fair to go by my logic then.
*edit* when I say you, I mean your group.
