How many fistweavers are you actually encountering, really?
You had my support until this emotional take. Playing castweaver into fistweaver is a nightmare. I agree. But fistweaver does not work in most comps, but excels in a few. Fistweaver in an environment like solo shuffle where coordinating CC is challenging can certainly be problematic, but not impossible.
Resto shaman, holy priest, and dev evoker are all capable of doing similar or greater damage from range with even less risk at times.
As a healing monk, fistweaver is attractive because castweaver is simply terrible. I don’t think castweaver (without drinking) can out nmana any healer in the game currently. Castweaver is the only caster that truly exists to cast as a healer and gets heavily punished for doing so.
You’re emotionally proposing to gut the most attractive healing spec my class has and offering no help for the alternative.
