With the last major update you put that band aid leaderboard before entering the forums with “medals” as a pretense that winning and having skill was still an objective in this game. Since climbing the top of the leaderboard basically required 3 maxed decks and continued play it was more of a list of players that had spent the most and still had interest in playing this game.
The new in game leaderboards while obviously non functioning drop that pretense entirely. A how many arena stars have you gotten leaderboard? Laughable. Rename that thing to “completed upgrades board” and drop the pretense that the game has anything to do with competition anymore.
