It’s literally life magic.
Mistweavers could be said to ctually being using the water portion of shamanistic power, except more exact, where as shamans kinda drop a bucket on their target, monks trace a few drops into whatever they need to effect.
Monks are the closest thing WoW has to water benders. And I mean literally water benders, as weaving it in and around is literally bending it.
Literally.
