I find that this website called ValScan is actually very good at this more nuanced stats like it includes play creation and man advantage creation rate in its rating and it also has other calculations like kills during buy rounds > kills during anti-eco. It's also got heatmaps of your games and other stats and is better than vlr rating and val tracking rating tbh.
ValScan also gives more rating for entrying and less for getting kills from baiting and overheating.
Here's mine as an example: https://www.valscan.gg/user/Zerphyr%230000 you can also see kills and deaths by distance and it honestly gives you a good idea into what your playstyle is like and what to improve on
But yes you are absolutely correct in your message, i just thought I would share this website which would account for some of your issues with rating systems
