Well yeah I would expect them to go through HC QA first. I was just trying to come up with a replacement for turbo boost, and stealth seemed like an obvious way to go.
Actually, now that I think about it, it’s such an obvious way to go, I wonder if there are any less obvious ways to go that would be cool. Teleportation and extra fly speed are already taken, and a -Fly power is unnecessary because the set already has one, but what else could it be?
