Since you're being so persistent let me reward you with a fun little puzzle. If you really are right you'll be able to solve it immediately and blow my mind.
When you start a competitive game of Overwatch you are matched with and against people in a similar SR to yourself, right? Right.
This means the pool of players you play with and against all come from the same distribution, over many games this will average to a Gaussian distribution centred on your SR (please see
https://en.wikipedia.org/wiki/Normal_distribution for more information). This means your opponents will take on this average (there's 6 btw) and your team will too (there's 5 of them), you are now the only independent variable. If you play to the average SR, this means your games will generally be entirely random, and you should net a 50% winrate. If you play better, your teams average ability will be higher, you will win more often than lose. The inverse is also true, if you play poorly, you will lose more often, your SR will go down.
From this it follows that over a large enough number of games to approximate your pool of peers to a normal distribution, your ability will be the only determining factor as it is the only constant (or inconstant if you're unable to play at a consistent skill level!
) when deciding the outcome of your games.
Now tell me, from these fundamental assumptions and the logic that follows, how does your ability to climb depend on your teammates?
Acceptable answers: Correctly identify flawed initial assumptions. Correctly identify incorrect or inconsistent logic.
Unacceptable answers: Anecdotes, random insistence on being correct, shouting about T500 friends who think playing Rein in plat is hard.
I'll give you a mark out of ten after you've given it a try, okay buddy?
