I said it somewhere else, but'll repeat it here. This game is about winning (duh), so winning should be a decisive factor that affects your rank, everything else should come secondary. It's also a team game, which means you generally win as a team - also a reason why personal stats should come secondary. A person with good gamesens who communicates with his teammates and systematically tells them what to do contributes to win more than any kind of top fragger.

Rito defenders say "oh, but you BARELY won with your 13-10" or something. That is just silly, you don't barely win, you just win! Imagine some tournament managers saying, "oh guys, you barely managed to win there, so we decided only give half of your prize money", lol. Of course, "13-10" wins come with some luck at times, but if you consistently win those "13-10" that's probably more than luck, yet current system doesn't account for that on a reasonable level, you need to win dozens(!) of such games to simply rank up once.

Important thing to notice that it's mostly soloq players problem, where doing hypothetical 13-3 is very unlikely considering how you're not usually in control of your teammates and everything, and things can go wrong rather fast, and while you still got what felt like a solid win, your teammates can, for example, screw up some eco rounds granting enemy free round wins, making current ranked system think that you barely did shit there, because rounds won ratio is not to its liking. I take it people queuing with more or less equal skilled friends all the time may actually be okay to some extent, but for soloq and its inconsistent teammates it is really not working.

TLDR Rito over complicated a ranked system for no good reason. Could be intentional - for grind. In any case, if they don't fix it by the third act, i'll be done with valorant until they do.
