Currently with crane you only generate Ki on a confirmed crit. On things that can not be crit you get 0 ki return even if you would have crit.

IE: Fight an air elemental - even if you jade strike the elemental it is still immune to crits - you can easily see the difference in how ki generates vs any other mob.

Suggestion: Change crane stance to generate extra ki on a confirmed critical even if the mob is immune to crits. This should give a little nudge to Dark stance monks who are dex/wind base so they are competitive with ki generation from fire/str stance.
