I don't see the reason opening drops to monster below lv.100.
The time a player spent under lv100 is relatively short. For a beginner, maybe a week? With help/experienced players will probably only take 2-3 days then they all move on to vd.
The only ones that will actually benefit from this below 100 addition is farmers.
FYI. The drop is too high. The original drop rate is fine. You added like 5 other ways to get low/med or even high. I don't see the reason of increasing drop rates.
In average, before the change, I'm able to get 2.5-3 per hour. Now it's like 10+
I think the update loses its meaning when it becomes Marco farmable. World boss/ mini boss are fine as it requires you actually go there but increasing the drop rate just to make the time spent on "Marco farming" worth it. This is just wrong.
