Is Treantmonk's homebrew "fixed" Monk overtuned?

[Merudo]

I mean, its not 'broken' but he's clearly comparing unoptimized monk builds against optimized fighter builds while failing to account for ki scaling, and so yes by definition this build is 'overtuned.' An unoptimized idiot monk getting 8d6+12 pretty much every round at level 11 with access to subclass options and stunning strike is pretty absurd. Doubly absurd if you count the Tasha's buffs.

Curious about what you have in mind when talking about an optimized level 11 Monk build?
