(All of this is just from memory, so there might be small mistakes, please point out if you find any)
The correct DPS class combination was predicted two times: S1 and S6. NEVER was the correct top DPS spec publicly known by the end of PTR!
The correct support class combination was predicted three times: S2, S3, and S6. Note that those were the seasons in which the support classes stayed the same as in the previous one; NEVER was a change in support classes completely predicted by PTR leaderboards.
I hope this sheds some light on how utterly useless it is to look at PTR leaderboards. Also, there has literally been zero testing on high level GRs on PTR; all the top players who have the knowledge and ability to pull off even semi-accurate meta predictions that could top PTR leaderboards are pushing on live. So please stop asking "WHAT IS THE S7 META". You might as well ask if we're gonna have snow on Christmas and get more accurate "predictions" now.
