Rather than pointing directly towards the ramifications of this change (least of all the fact it wasn't included in patch notes), it flat out cannot be intended behavior. As this has not been changed in the around four years the content has been within the game, it beggars belief to think this is an intentional change. This should be adjusted not only because of the negative consequences it has towards the content it is applicable to, but because it cannot be the behavior working as intended or as it should be.

The fragment already is highly in circulation among seasoned players, so changing the drop rate so dramatically only affects those new to the content in a severely detrimental manner. This change needs to be reverted to its original 100% drop rate, if not just because of the negative impact it has on those attempting to engage with this content for the first time.
