While cutting out a dot stance was positive, there is still a need to constantly swap between movement speed (pulling, exploring, maybe fighting depending on the numbers) and sun/moon (fighting) which is tedious. I suggest folding movement speed into the body mastery system instead (so yeah eventually always on, but it's a small amount). If it were up to me I would go even further and fully remove Wind and replace it with a niche third utility stance, for example maybe one where you focus your mind to see hidden, see invis, sense magic (buffs), etc. That way you can mostly just focus on offense/defense stancing which is more stable.
The 2HB skill sounds cool and I would expand on that further. 2HB for optimal defense (something else added baseline, not all CD/gimmick gated), DW for optimal offense, would be a pretty cool general distinction.
All sounds good otherwise. Some concern they won't have enough ability slots to use all of their kit.
