@dgxg Unfortunately, you've misunderstood how drops work in this game. Not every item has an equal drop chance. Imagine it more like a 6 sided dice. If you roll a 1, 2, 3 or 4, you get money. If you roll a 5, you get a ticket. If you roll a 6, you get girl shards. When they add in gems, it'll replace the result for 3 and 4. You'll get shards the same amount of times you did before, but less money, because those drops are replaced.
Now I also do not know this to be fact, hence my request for you to have data. It might reduce them, it might not. At this point in time, noone has provided any evidence either way (understandable since people are busy doing other prep/testing work). I figure people will start a new measurement in the drop rates once this patch becomes live, but it'll likely still take a couple of months to get enough data for various event types (and/or regular boss girls).
