These are well thought out changes, can't dispute that but for me they would mostly be uninteresting. Sss and tk have niche uses right now but removing those uses so you can have an extra button solves nothing. I like the chakra change but not the brotherhood one, I like being the theme and feel of the skill and for every time I get very little chakra there is another time where I get lots.

Likewise why take the tight timing requirement from pb and replace it? Gearing correctly so you can hit 6 actions and timing your cast so you don't press too early and waste time is a part of optimisation that your change would remove. While monk has problems it's at least in a place where optimisation feels satisfying due to the difficulty of some parts, I wouldn't want to go back to easy street.
