In my opinion for non-professional play (casual and ranked), these kinds of tools should be outright banned. The game goes from “how can I improve myself and play better” to “let’s expend the minimum effort possible solely to win”. You’re not playing to your strengths but just to the opponent’s weaknesses from the get-go. That’s just incredibly boring. Just because one can have a shortcut to a win doesn’t make for better or more interesting gameplay.
Regarding professional play, the teams have the resources to do this given the limited player pool and they’re also at the pro level anyways.
I feel like gaming stats should have way better privacy options in general.
Data from games is such a good way for people to get into programming and data analysis (Speaking from personal experience).
It's easily accessible, real and has a decent level of complexity. Would be a shame for it to go away because people want to hide their data.
Realistically speaking this kind of stuff doesn’t really matter at a lower level anyways- everyone’s bad and makes dumb mistakes. And it doesn’t help to know about data if you don’t know how to capitalize on it.
I can’t recommend getting into MOBAs/ARTSs solo, but if you have 2-3 friends they’re quite a blast.
There is a lot of summary stats available, but the most useful one from personal experience is the win ratio. If the data tells you that one player on the other team wins 70 % of the games, then that's usually a clear indicator that the ranking of that player is most likely lower than it should be.
It might just be a better or worse player overall, so adapting to it might not be possible, except for knowing who to put pressure on.
