Yeah, Imperium is serious business with their Psykers. Doesn't mean they are stable, by any means (Well, Librarians typically are, but they cheat), and I think a Commissar cadet would blue screen at the sheer psyker rawness going on.

Precisely! Just smite/throw the environment at things/mindbullet your way to victory/death. And hey, becoming an inside-out horror monster could be an advantage if you do so in the midst of the enemy ranks. Since all the now inside-out horror monster cares about is murdering everything within arm's reach, and the sudden daemonic abomination miiiight be a bit more pressing than the guardsmen rapidly running away. Pushing powers, while cool in concept, really doesn't seem overly justifiable. But hell, more power is always good.
