Okay i know what you mean i will do my best to explain it but i have a hard time explaining things (will try my best)
I have 470 hours played on my MW monk and i have not played it since the end of legion when they changed soothing mists so that you couldn’t move when casting anymore.
This change for me i think was what stopped me playing because it was such a small change that had such a huge impact. They also added a cast time for Eternal Flame for holy paladin at the end of Mop which i didn’t like either and have not really played holy paladin since then.
I find it had to move and position well on Mistweaver now but maybe that is because i was so used to playing it a certain way, i find the whole casting soothing mists to get instant cast enveloping mists/vivify very annoying and chunky the only thing i do like about the current monk spec is essence font and renewing mists - I struggle with mobility and positioning and have done ever since they changed SM to a none mobile ability but i do get that is a me issue.
I am talking about mythic plus here though as i only ever did challenge modes and mythic plus on it and did some lfr for the legendries but raiding was on my priest.
As far as the MW melee healing spec goes that is just a rabbit hole i do not want to go down at all
