I never bothered with the earrings, mostly because I can barely even see them on my own character because headgear and hairstyle.

The rewards are for more casual players but also for free trial players as they can get early access through these tomestone events for mounts. Like if a person is on a free trial account right now, they can get access to the ruby gwiber and the ironfrog mover mounts even though they otherwise can't access shadowbringers content. I can even attest to that being a thing for years, like I remember when my account was free trial and the level cap was 35, had to grind sunken temple of qarn 17 times just to get the Ixion Clarion (stormblood fate content).
