I'm nitpicking but I think that roll created too much distance. I don't like the slow time effect when picking the new stance, in my opinion that takes away from the pacing of the combat. If shyt is deadly, you shouldn't get time to slow down and think, those should be instinctive switches. It also feels like it takes him a long time to get back into the Water Stance after attacks. With how fluid of a style it seems like it'll be, you'd think the conclusion of the combos would put your body closer to the initial state. What's more, after the combo that kills the second guy, I feel like it let's you parry the third guy too quickly. Just looks kinda off. But like I said, I'm nitpicking.
Would be cool if the weapons actually cut the foliage as you swing, but maybe that's a detail that will have to be picked up in next gen games
