That's a good idea.
Wouldn't hurt to have an all time leaderboards in addition to seasonal leaderboards.
Just saying', I'm not a fan when it comes to playing much in a short period of time.
Last time I did this was the dragonet quest and I took a 2 weeks break from PL after that.

When I tried for leaderboards I took my time in PL. Would be nice for long term players to work towards to
