wherever there are people talking about fighting games, there are always people obsessing over their rank or their performance in ranked mode and i just don't think it's healthy! especially if the game is new, or if you're new to the game or genre.
i get why people are drawn to it- modern FGs always put ranked front and center, and act like it's the endgame. your rank is shown under your name and character midmatch, even in non-ranked modes. on paper, it's cool to see your relative power level among the playerbase, to set goals, and have the game itself acknowledge your growth! but the reality is that it can do a lot of harm to your mindset and growth if you're not mindful about it.
i'm not saying DON'T play ranked-- i think ranked is great for getting quick games (if your game has a populated ranked mode that is) against people ROUGHLY at your skill level, without having to put much effort into finding matches. it's also good for practicing your "layer 0", or adjusting during a first-to-2 set.
i think it's a little hard to learn much in ranked, unless you have the right sort of brain for it. the maximum 3 games is short enough that you and your opponent can kill each other with silly gimmicks, then it's off to the next set where you're probably fighting another character or player. it's so easy to mash into the next set without thinking much about what actually happened in the previous one.
if your rank goes down when you lose, it can feel bad, and that makes losing itself have more negative associations than it really ought to. people who spend a ton of time in ranked often take losses worse than those that are playing in rooms or casual matches.
but the main reason i suggest against living on ranked is because it's just so impersonal! getting beat up with no feedback sucks, and it's easy to forget that another human is on the other end and probably feeling sick as hell for the shit they just hit you with.
if you have a community or friends you can do so with, i really recommend playing longer sets and chatting about the games as you go, either on voice or through text! for me at least, the human element makes all the difference and is what it's really about.
