It is not in the official post but changes can be seen in the wiki and in-game.
Also, why did you make throw shuriken not only chug sp but also miss? I am not only wasting time sitting waiting for SP but also waste zeny. The Buff to damage does not justify the trade offs when you compare the changes made to the Six Main Classes. You could at least add a DEX/AGI/LVL scaling to dagger throwing practice like what you did to the Falcons/Aura Blade.
The nerf on "Throw kunai" to miss is justifiable but the damage scaling per level sucks. 100% on level 1? Sure you max it but still.
Melee build still sucks. Haze slasher still sucks. At least make level 5 shadow leap free to cast/make sp cost scale off distance travelled.
The ninja is definitely the sitting simulator class.
