Of course I am disappointed to be "robbed" of the chance to End a season in the top50 for once. On the other hand, I understand the problem. Imo you should have rewarded those who managed to be top50 from a lower league at least with some cards to be fair - it requires skill and was a time investment as well.

Anyway, I am looking forward to separated leaderboards. This will be great.

One thing that will be very important to prevent:

That people play and accumulate ranking in a higher league and drop down to dominate the leaderboard of a lower league in the end of the season.
I would like to compete in gold league only if there are some prices, but NOT if I am getting the prices stolen by champions league players in the end.
