Severans aren't spent or the Spinward Front would've collapsed under Grimtoof's constant punishment by now. It's only because they're taking the brunt of the waagh! that the Imperium has enough resources in the area to fight them rather than having to focus everything on the Orks. Although they are under a lot of strain due to having to fight both the Orks and the Imperium so yeah, they'll be spent real soon.
