Any way to view historical PvP data? (need yalls advice)

I am writing up a commentary that i might post to my YT channel, and am trying to do some research, and wanted to see if you guys knew of any resources, where I could for example view leaderboards/statistics from previous patches, as far back as Cata/Mop if possible

edit just found that arenamate has an archive that I can look into

Oh, Arenamates is alive again.

Are you still able to find ladder data on Arenamate? I could only find cutoff data but nothing on ladder stats.
