Hey,
I used the following Lua script instead of the pre-defined "Chi" in the Fighting Class:
Add as Condition 'Lua Script':
Chi = UnitPower("player", 12); if (Chi >=4) then retV = "1" else retV = "0" end
[Return value research]: 1
[Return value var]: retV
You can change the Chi >=4 in brackets to whatever you want. Chi > 1 or Chi = 3, works with all operators.
If you have any questions I can also send you my WW monk profile. Works like a charm
