I just wanted to say your class has been Tiered. Other than sixth-level Blends and fifth-level UPs, it has no Tier 1-2 stuff, which is a good thing. A lot of abilities are missing (Ex), (Su) or (Sp) tags though. Without those, an ability is automatically (Ex), which would be ill-fitting on many of them. Mistwalker is illogical in that it works like air walk, but doesn't actually allow you to walk on the air (since it only works while you are standing on the ground).
