Don't get me wrong, I really like the leaderboard system, but I miss some ranks in between.

The skill difference in immortal is too big now. Also, I feel like there's nothing really to achieve anymore. Radiant is far away once you're immortal. We need a few ranks in between to feel like we're making some progress. Basically it's 4 full ranks to radiant (400 RR) that get higher the longer the act goes.

Immortal doesn't feel worth like before anymore.
