[Frozen]

People want to cut through the grind with paid items because the grind is exactly that: a grind! I'd say not to even bother making things like that a paid feature. Make getting to level 60 fun!

Barring that, there are a few ideas I've seen in here that could help the original issue. Making the shards shared over the entire key rather than the single character could do it. Alternatively, spending Cypelle to get the remainder of the shards you can't find or can't be bothered to get is a good way of adding a new Cypelle sink.
