Hello wind BD! Nice to see our rare breed still exists.
I definitely agree with most things here. The new fused Wildborne Soul Badge helped smooth our rotation by a lot and made wind BDs way more enjoyable. I've also experienced the same issues on Dread Prince Sobu in Warped Citadel, and I really have no clue what's causing it. At first I believed it was due to being in Spatial Isolation, but I experience the exact same issue when on the outside. It seems like not our passive skill nor the Liberty Soul Badge works properly.
I also agree about the issue with Wind Spirits. Changing the Squall effect might not be a great idea. If anything, I say the RNG effect on Rolling Typhoon to regenerate a Wind Spirit should be changed to always happening or by changing Whirling Scourge to generate an additional Wind Spirit over time. Not sure how good the idea of the RNG being removed completely is, haven't really thought it through.
As for Simple Mode, I use it as well, and the added Sunder when Rolling Typhoon is unavailable is a lifesaver. My only issue with it is that, well, it just seems like a bad way to design our most high damaging skill, and there's no way to adapt to the Rolling Typhoon's RNG Wind Spirit if you're parsing unless you always do a Sunder inbetween which will end up as a damage loss.
The two things I'd disagree about is the Nacha strategy and our damage output.
To start with Nacha, even if it's intended for Rolling Typhoon to not remove stacks of Demon Blood, it seems incredibly weird considering there's no issue for Lightning BDs who can use Flicker and Lightning Flash. Having to compromise by using LMB or saving Wind Draw (that's the name for C, right?) to use our own Flicker and Lightning Flash is just meh.
As for damage, while I'm far from an expert in Tower of Infinity, I can definitely see Wind BDs being proficient there. M'ao though? Not really. Looking at the current leaderboard right now, pretty much every single Blade Dancer is using Lightning. Maybe that's just because most people prefer Lightning (god knows why they do that), but I'm yet to see any Wind BD reaching one of the top spots.
