So from what I've found so far since the change:

Cluster is no longer 100% (As others have mentioned)
Crystals seem to drop in clumps of 5 or 7 now instead of 3 or 5 (Has anyone gotten 3 since change nobody I've spoken to has yet but thats not many so could be wrong)
Atomos seems Stronger and Has more HP
Cluster hand in is still 3k (I had one from before maint just so I could instantly check if/on the nerf)
Crystals still 1k
