What after rank 99?

[Fractorial]

It has been suggested though.

Medals, medals everywhere not a reward to get

I would suggest that a player can still receive keys as a reward for every x amount of points earned after reaching Tier 99. It could be every 10 billion points or so.

And having the same amount also… quoting from GuestUniverse:

No, from tier 98 to 99 is not even 100 million points away. You are probably mistaken with the total points. Probably it should be 250 keys per 100 million points after tier 99.
