I guess the fact that they are not visible beside spearfishing (with now the minigame blocking the view) could loosely make sense. but the other problems remain.
Saying "it's nice you don't need to upgrade your gear" defeat the point of an mmo.
Grinding for stuff is the base "content" of the game.
If we take that to senseless extrems : no need to upgrade any gears ever either. PLD shield can be disabled and be glamour only(since the shields doesn't affect Ilv for jobs that don't have it) and who care about new relics, you already have 6 glowy weapons.
