I think the double-weaves are a lot worse now so it's pretty unfortunate that you tried out SMN in its current state. It was a lot simpler and steady back then and honestly as a SMN main since 2.x, the amount of double-weaving and sometimes triple-weaving I have to do now is tiring.
They are planning on making the job less busy (probably with the ogcds) so I hope that makes the job more welcoming to play for people, but yeah you might want to spend more time with it because I was in the same boat back at ShB launch, but I'm used to it now (but it's still a struggle).
