I think they should retcon Spartan Op's, also quickpatch the Spartan IV's in campaign with regular marines. Remove Palmer entirely, she's a joke.
It's hard to imagine any group of professional creatives ever looked at this collection of characters and thought they would be likeable. Which leads me to think (hope) that they might all end up getting killed off anyway.
I think it's odd there's nothing from McFarlane of the SpOps characters. Hopefully that's another indication that they're not going to be around too long.
