A nerf is fine
Making hammer a loss, messing up the starry window including starry’s core skill and making creature parts only a gain with mog/madeen is messing up the job
The PAINTER job is basically completely disincentivised from painting in favour of spamming filler
A job can be mathematically fine while being weird because you are actively disincentivised from using its main mechanic, like imagine not wanting to jump on DRG or not wanting to use your melee combo on RDM
