Is that site up to date with info about the pvp life?
Yes. Well, kind of.
It directly pulls from what Blizzard provides, so I guess it depends on what you’re looking for. Keep in mind most people are built for rated play which may not be the best for, say, unranked battlegrounds.
Back when it had an unrated solo shuffle leaderboard (which, because there was no rating system, just showed whoever had the most games won, which was usually also whoever played the most overall), the data seemed to be accurate but incomplete because it only included players whose name had been searched on their website.
idk if that is also true of their rated leaderboards though
Random BG stats don’t seem useful because in the case of honor level it’s usually just people who play a lot or in the case of winrate people who exclusively premade.
Like, look up somebody with a 90% wr in random bgs then compare it to how they do in actual competitive brackets.
