No, I realized I flubbed up with my comment about pyrrhic kleos, where I didn't consider dual wield. It is very possible that I noticed low tp return hits all of the time in ballista, and just assumed it was the same for WS into shadows. Ballista isn't good to go off of because you're being hit by multiple people and spells while concentrating on your next move; it's distracting. Even if it is a habit to check tp after WS, it is probably fairly easy to mess up in ballista.
