I think you shouldn't have removed the cooldown reset, i think non-upgraded one should keep cooldown reset but only in defensive stance, the upgraded one should have extra action on aggresive stance or cooldown reset on defensive stance but that's just my opinion because the extra action is pretty powerful even with only 2 usage's.

oh hell yea, all these changes feel so right. Duelist is likely the weakest hero of the roster which sucks since she's really fun, these changes make her skills less of a pain in the arse to deal with. Feint granting a stance is specially cool to me, means you can open up with that move instead of touché for example. The inverted movement in touché, from what ive thought up in my mind, works specially well for lunge spam which is a big yes in my books. I wouldn't mind seeing Disengage's dodge getting buffed a bit further, like an extra dodge token, since to me it still doesnt feel like a great button to hit from my own experience.
Again! turning into an extra action makes so much sense, its no longer a useless button!
Coup de Grâce being available on aggressive for some extra punch is fun, more gun is always good.
great stuff dude, thanks for posting this!

I think it'd be interesting if you changed the Academie Ring to make you switch stance every turn
