Since STS doesn't publish a handy guidebook we have to rely on anecdotes and trial-and-error. So unless someone can show definitive proof either way, the debate isn't over.

What about the hit chance stat? We can only see the dodge stat. It's probably a safe assumption that dodge and hit chance stats interact somehow.

Maybe you didn't dodge that fireball, maybe the mage just missed. Maybe fireball stun is chance-based, counter to the way the upgrade reads. Maybe the Spacetime Engine's attempts to sync gameplay fouls up more than we realize.

So... ya know.
