@delphs As a workaround, you can use this custom search string to find games with high-rated players.
To run a custom search, you check the box for "display search query," which shows a one-line text box. You paste this in to the text box, and press enter to run the search:
I just took the top 65 names from the ladder leaderboard, these are your high-rated players.

This search string only returns 1v1 ladder matches.
If you don't want to search JUST ladder matches, you can delete the very end of it (which I put in bold). If you get rid of the bold text, it will include TMM games, global ranked games, and other games.
If you want to look for TMM games only, replace the bold part with this
;name=="*team*"
It will pick up some false positives, but all TMM games presently have the word "team" in the title.
Or you can put some other custom search term language in. If you craft a custom search with the box checked, you can see how to set up your own search.
