I have been taking screenshots of some key ranks in the events leaderboards since the new event format was released. The scores I am tracking are those of the players who finished 1st, 2nd, 10th, 50th and 100th in the event.
(Here is the link for events with 10 stages: Tracking of Event Leaderboard (Top 100) Master Scores - Legendary, Epic and Rare (10 stages))
1 - 1st
2 - 2nd
3 - 10th
4 - 50th

If you spot any typos/mistakes, please let me know. I’d also appreciate it if you give me the missing data, if you happen to have it.
You can see that events are getting more and more competitive which means that it is harder for players to achieve a higher rank.
Do you think that the increase in scores is because of the appearance of new heroes (e.g. Nordri)? Or it is because the rewards make more and more players compete? Is it time for a change in events?
Edit: Special thanks to @Peterenp for providing me with most of the missing information.
