I pretty sure I'm not the kind of people you're talking about, but it could be interesting to gather a set of advices for ranked modes. Not the basic "don't jump in a middle of battle", but actual strategies.
Maybe not. My issue isn't "this person hasn't mastered the mechanices yet?! git gud scrub!", but rather "this person picked up the rainmaker and ran backwards to our own goal when the only objective is to do the opposite".
Just things that show someone isn't ready to learn ranked modes, but not that people are still learning. Learning is fine.
I would love if they had real competitive advice for ranked. Especially since Nintendo wants this to be an esport.
Even better, I would love if they either let me pick my teammates by adding Squad/Twin to Ranked, or if they decided to judge rank up more so by individual performance rather than 100% on team win/lose results.
That way better players get ranked up quicker, and can leave the people who aren't that good yet alone to learn. Everybody wins. It's literally what other games try to do.
Even Mario Kart 8, though the matchmaking algorithm itself doesn't work well, has a better design to it's rank system.
This is solely because they start everyone off at 1000, rather than 0, like Splatoon does. Good players go up. Better players go up faster. Folks who need easier opponents drop in rank appropriately.
By starting everyone at the bottom, you make this separation process take longer, and produce inaccuracies.
