I suppose, when you look at the game's current state and how the developers have been interacting with us, you're totally right.
If you must look at everything through DPS, consider that the Bole used to be more opportunities for an AST to focus on DPS, since it reduced all incoming damage for a time, meaning it lessened the need to heal. This was the same in solo content and in party content. With regards to the job itself, it was a boon. It just wasn't a direct boon to the DPS jobs.
