Could you tell me why?
How will you get the data to balance something if players cannot compare before/after updates in many builds.
For example, there has been two nerfs in Crus HF build (SoF 20->10, Ivory Tower nerf) but the non-season leaderboard only shows the record of the players before it get nerfed because you didn’t reset leaderboard. Mundunugu is the same situation.
And I don’t understand why is it technically so difficult for you to reset the non-seasonal leaderboard right after the update.
