It was originally a poorly conceived skill that was designed to upkeep and build Greased Lightning. Its requirements to actually work were so narrow that it was useless for its intended purpose and it in conjunction with the other questionable Monk changes basically broke the flow of the job for most of the expansion.

After they killed Greased Lightning it became the weird vestigial skill it is now, which is to save Twin Snakes but only after you've Formshifted for Formless Fist and capped Chakra with Meditation. It doesn't justify having a slot on your bar.

It's pretty questionable if there's anything they could do to salvage it in the future either since the typical point of a channeled skill like that is to build Gauge which Monk already has in Meditation. Hopefully it just gets deleted and turned into an Emote.
