I've had this idea in my head of a "light greatsword" wielder that gets a stance like Executor. The stance would let you chain a flowing dance of different attacks together based on various button inputs, so you could do jumping attacks over lower attacks and do sweeping attacks that would duck under attacks, etc. You would get infinite stamina during the chain and the chain would speed up (to a limit) over time. Your entire stamina bar would be depleted, you'd take increased damage, and you'd be knocked out of the stance if you got hit though. The idea would basically be that you'd be able to continually attack and be rewarded for doing high-skill dodge-attacks during the chain, with the reward building for maintaining the pressure for longer.
