Most of these suggestions don't actually alter current monk's gameplay. For example, Six Sided Star as just "Steel Peak but stronger" is just another bog standard "Use on cooldown, prioritize in burst window" OGCD. These get cut. It's not just Monk, this tends to happen across the board (I don't agree with it - I miss the shoulder ram animation - but thems the breaks)
On a personal level, I don't think the 50 and under Kit needs much work. Maybe a little number tuning (There's a pretty good analysis on Leaden Fist somewhere around here), but the FFF RRR weaponskills don't need much tweaking.
Moving forward, my own preference would be making Chakra and Greased Lightning play off each other more. An optional avenue would be having Fist/Riddles play into it somehow.
For example, lets take Anantman and Six Sided Star and create a very basic play between the two.
Six Sided Star
Weaponskill
2.5 Recast (standard)
Effect: Deals "X" potency (Slightly less than the average of the mainline combo). Grants 1 Chakra.
Anantman
Ability
45s recast
Cost: 5 Chakra
Effect: Grants Greased Lightning IV.
From these two changes we have a few implications.
Tornado Kick can be used now. Anantman allows one to TK at anytime it's up and maintain Greased Lightning - Provided the Boss isn't about to jump.
If a Monk needs to delay a GCD in the main combo, Six Sided Star allows this while also serving as some Chakra management.
To me these are good changes to the Monk's baseline kit. They start building a base of prioritization of Chakra and Greased Lightning, from which one could extrapolate more of the kit with that end-goal in mind, which does allow us to bring back bog standard OGCDs by building them around this concept.
Steel Peak, which becomes Forbidden Chakra with 5 Chakra.
Howling Fist, which becomes Enlightenment with 5 Chakra.
One of these have an independent CD from their Chakra variant.
One of these shares the CD with their Chakra variant, but gains significantly more strength.
With that, we have created a basic resource conflict with the Chakra skills, between the two chakra skills and Tornado kick (through Anantman).
