A) As you already tell us at the road map “The next 90’days” section, you said that the first 300 (and not the 150) would claim the 5* featured champ.
90 days are over and no announcements.

“buffing” drop rates and give us the nexus crystals has no use for the majority of the players. Only if you are whale and you open >50 crystals (10$ value each) every week.
Make a change that is worthy:
Upgrade the drop rates at 6*. We pay 10$ (Unit value) for each crystal and there are still 3* inside.
I understand that RNG is part of the game , but you have to make gap smaller.
