So, I have seen it said a lot. And it makes sense.
Let me explain…
You say that the match maker groups you with “people of your own skill level”
yet that is demonstrably false in most cases, but that is not the topic.
Let us say that they group you with people of your own skill level.
That means you should have a perfect 50/50 chance of winning. You don’t, but go with the idea.
So you win. What does that mean? It is supposed to mean that you are better than your opponent. You gain some SR, your MMR changes a bit, and you climb.
So that means you are “gitin’ gudder”
But that would mean that when you lose, you suddenly got “badder” than you were the last match, or that the enemy team “got gudderer” than you did.
So let us say that you started out in Sub 500 SR. And you slog your way through that, then trudge you way through Bronze, and Silver and Gold, and Plat…But you just can’t get into Diamond. According to the current logic, and the way people think the system works is that you are either going to be hard-stuck in Plat, or you will climb. Because that logic from earlier means that you are in Plat because you deserve to be there. You worked for it, so now Plat is your reward. Your home.
So why do you derank then? Did you suddenly become a worse player? No.
Did you suddenly forget how your left-click works? No.
Nothing you are doing is any better or worse than what you did to climb up to Plat. Your performance is just as stellar as before. So why can you not get into Diamond. The general logic is that you need to “git gud” but you already did. Afterall, how else would you have gotten to Plat?
But what if you fall down. You go to mid Plat, to Gold, to low Gold, Silver, low Silver…Using the same logic as before, you already “got gud” and climbed to plat, so you should stay there until you get better, right? If you were able to get there in the first place, you should never be able to get de-ranked because Gold would be a cakewalk for you, and you would just climb back into Plat. So how did you end up back in Silver? Again, using the same logic, if you fell back in Silver, you belong there. But you climbed up to Plat, so you deserve to be there as well.
How do you belong in Silver and need to “git gud” but you climb into Plat and you are called a crappy player?
How can you deserve to be in Silver and Plat? How can you be hardstuck in Plat, but then turn around and be hardstuck in Silver?
The answer is that you can’t. You belong in Plat, because you climbed your way up there. You worked your butt off, you watched all those videos, you learned everything you can, you worked on your positioning and call-outs. You work with your team and communicate. You took all the advice of the pros and top-end players, and you ran with it. You got to Plat…But Blizzard loves you having a 50% win-rate, so guess what happens? Oh, but wait, that does not exist.
The system is flawless and perfect and you belong in whatever rank you go to, despite your work in much higher ranks.
Nevermind that pro players, and YouTubers (?), and people in Diamond to GM all say that there are some pretty messed up issues with the rank system…
