None of the items are particularly an improvement and the wyrm ash, the juice just ain't worth the squeeze.
That "hourish" you give up to go do a dragon costs as much as the money you make back, IF your ash sells, and IF it's not undercut. You just break even.
You make the mistake of living in a bubble, and thinking your perspective is the only way things should be done. Some people aren't as efficient as you, some people aren't maxed gil like yourself. Some people want the items, or want to earn the ash rather than buy it for their own purposes. W/E their reasoning for wanting these points, it's a hassle, it's a chore, it's supposed to be a game.
(kinda goes full circle back to a previous debate we have had that we both know each others take on)
