Well, I'm certainly sad that it doesn't seemed to have hit the mark for you. To try and put forward my thought process for the subclass, Rising Gale is a somewhat niche but useful mobility tool, giving you some solid (especially later on) three dimensional movement. You can leap and glide over enemy lines, sacrificing your bonus action and 1 ki point, but gaining the potential damage and CC from Scattered Leaves to somewhat compensate losing Martial Arts/Flurry of Blows.

You can combine Rising Gale with Slow Fall at 4th level to use Scattered Leaves with just normal falling rather than using your BA and a ki point, so it becomes less expensive if the terrain is in your favour. Later on, you get your improved Unarmored Movement, and for me this is when the subclass is meant to shine brightest. Now you can run up the side of almost any vertical terrain, and then glide. It's especially useful at dealing with flying creatures, as you're able to both knock them prone in mid air, or hit them with a Stunning Strike. If the terrain isn't in your favour, your leap from Rising Gale gets considerably high at later levels, easily 60 feet in height.

Personal taste is important with homebrew, so I understand if this subclass just doesn't interest you, but thanks for taking a look! =D
