Ranks are overinflated since new rank system was introduced. Ranks should experience deflation.
Time for some quantitative easing, bail out the lobsters.
On a serious note, the current ranks system is based on percentiles. They are inflated since Steam because ZK has a bigger community. There are also more bluebloods and royals now because in the year since release, the slower learners in the Steam cohort have finally sorted themselves to their appropriate levels.
(Some of those have shot up near immediately or very quickly, like UltraGodzilla or Sparkles; but the majority takes a longer time).
