I'm glad that most things are remaining unchanged. However, it seems that item 5 is aimed at essentially lowering the spawn rate of NMs and thus the drop rate for gold chest for large camping parties. This would have been a reasonable decision pre-implementation. If I'm understanding this correctly, it seems an unwise decision at this point - as the change specifically benefits users that have heavily farmed diadem post release and puts future farm parties at a comparative disadvantage. However, I could be misunderstanding the way this change will function.
