Why? (Destiny)

Well, previously if you got a duplicate drop, it was possible to use that to infuse your old one, and it would only cost 5K glimmer. Now, you won't be getting dupes of these particular items, so anything you can use to infuse them is guaranteed to need "enhancement cores" as they're apparently called now. It's not the most critical scenario IMO, but it's a thing.

I don't think you ever needed masterwork cores on exotics anyway… or maybe that was just if you infuse an exotic into something else.

I think it's cores, shards, and glimmer for infusing lower into higher quality, shards and glimmer into the same quality, and only glimmer for the same exact items.
