Okay so what is the problem here? You just said that if you do well your team does well, usually meaning you win. So basically if you carry you win, and that is the majority of your personal experience with the game.
And I'm saying that people I play with or people I've seen play do better than me, and they
still have a harder time than me.
By the logic you're going by, I'm better than most people I talk to about ranked. But I play with them and I know this isn't true.
And then there are people who I've talked to who don't use my simple strategies of flanking, waiting, or baiting, and when I tell it to them, it makes sense.
But what, am I supposed to educate every other player on shooters 101? Randoms that I can't communicate with?
I said when I do well, my team usually does well. Yes I can carry. But that doesn't mean my team gets away with being bad.
If what you're saying is true, that this is all about solo ability, then where are all the people out performing me? I'm usually top of the board or even with my team. Once again, are you saying my wins manage to make me better than most people I've played with? At some point, shouldn't someone else step up to the plate and carry the team? You know, by virtue of your logic being "individual skill matters most".
Or maybe, just maybe, bad players are bad, and since I've spent less time on ranked, I've ran into less teams I couldn't carry that extra mile, and ran into a couple of teams that knew what they were doing. Maybe I'm at the top of the scoreboards for the games I win because I keep running into people who aren't as good as me, which I see often, and I'm sure happens often for most other people, from what I hear.
Oh, and just because it doesn't effect me doesn't mean it's not a problem. Luck is a factor - you have no way of knowing how skill your teammates are. Sure, the nature of solo queue means you need to be ready for anything, but that doesn't excuse the large percentage of bad players. There is a way to eliminate that luck, which isn't in the game yet. So until it gets here, the bottom line is that ranked is basically a grab bag for good players if you can find them.
In the end your logic is silly, since even if I was somehow really amazing...
1 good player vs FOUR good players is still uneven. >_>
EDIT: I gotta stop writing giant posts when I don't even proofread 'em, jeez.
