And rankings like this which only look at volume of appearances rather than anything more nuanced only exacerbate the problem of the feedback loop.
There's no evidence to confirm or deny that but I can't see it helping, no.
A ranking that said "these are powerful and played a lot, these are powerful but not played because X & Y and if that changed then they might get used more, these are actually less powerful but see play sometimes because of Z" is quite constructive.
A ranking that says "these are powerful because they're played. These are rubbish because they're not played" only reinforces the hivemind, inadvertently sucking more players into it.
Sadly I had this happen locally. A person that just started was putting together lists so I asked what made him do it, he was relatively new at the time, "Saw this post on jousting so I used those numbers to put this list together." I then destroyed him with "inefficient jousters" and he was flabbergasted. I then explained to him that those numbers were only 1/4 the story. Needless to say, he is a much better pilot now and uses these types of posts just to see what might be in an out of town meta.
