I think the reason to play it should be the same as any other job: because you enjoy the fantasy of it. It's difficult dealing with FOTM players as a dev because if a job like SMN is too viable then everyone plays it for easy performance and they start to complain about the game being too easy or boring. That's part of capitalism and recognizing the weak will of the playerbase for what it is. It should be viable, but it's delicate due to most players "not caring" about what job they play as long as it is the best performing job.

Damage numbers and combat logs kinda ruin the game. All this stuff should be under the hood completely and health bars should just be without values or percentages. Base engagement with content on having sufficient ilvl and leave it at that. Destroy the parsing community.
