My suggestion is that when an event arrives (like Halloween), you should only be able receive the event's Cubelet type and not the normal ones when playing games, since the event is limited to once a year and only stays for a month, even if the drop rate is going to decrease, in my opinion that's better than grinding for hours and then getting a normal Cubelet, therefore not unlocking the loot you wanted in time.
Let me know what you think!
