It's a great idea being well executed! It kills so many birds with a single stone! If you are hunting a full armor set or to complete a weapons collection it's there for you. If you want more rolls of a weapon/armor it's there for you. If you are helping your mates to clear the raid several times a week it's there for you. If you don't want to run the raid on your alternative characters and prefer to stick with your main it's there for you. If you got just a single character it's there for you. It's so great that now every (new?) raid should have it!
