Your legion trait is the same as before.
You now have terranic greatswords at home

Gorgon terminators lost bolters (probably a mistake) and can cause a status test if they pass a save during volley fire. Also have 3A and FNP making them very tasty.
Immortals kept FNP and have expendable.

All in all IH seem more or less the same as before, you lost the grav moritat that could kill titans in one turn but thats about it.
