Only 5 gems out of that those no brain of service dev really do well LOL

It's about spending.
If you can remember PPS do get rank 6 or 7 during early period of collab time with FKG.
Now they just drop out from Top Ten or wandering around 9-10 place.

Before that Aigis do run up to first too around time they sell Silver pack something.

Don't know what happen with OI but someone in dicord do mention about some deal that do help OI on top spot.

And FKG just suddenly got 1st place from nowhere when fabulous rainbow deal appear.
