Recently I went 7-1 withRosalina. I think my problem is o get nervous against real people and just forget everything I teach myself.
I had this problem as well, being able to play decent against familiar friends and family and then heading into For Glory but then do to my nervousness it's like I completely forget any decent sense of play style as if I 'forgot' how to play and I would suck, which made me not want to really play on For Glory.
But then I'd always watch my brother play and I asked him how does he not get so nervous facing real people online. Then he told me, 'Think of it as like fighting a really hard CPU.'
Give or take typical For Glory spam/camp shenanigans of course.
So yeah it's pretty much the mindset I stuck with now to the point I don't really even flinch at jumping into 1v1 For Glory anymore (I mainly stuck to team battles before then so I had like 3000 matches there lol). But now I prefer 1v1 more.
Also since this is kind of under the same blanket in the topic of not being able to win and stuff. When I first started playing For Glory 1v1 I mainly stuck with Ike for the most part, being my main and who I was good with. And when I did try to switch off to some other characters that I enjoyed playing, I would just lose, making me want to stick with Ike more.
But again watching my brother, I see him switch between several characters (he plays Marth, Link, Fox, Falco, Donkey Kong, Mewtwo, Lucario, and Captain Falcon). And yet he's good with all of them and can still win his matches. So I asked him what does he do to learn new characters, does he watch videos or read guides and he's like nope. Then I said, you just jump straight into For Glory with them? And he's like yep. Then I said, but what if you keep losing, then he said he keeps playing them.
Which was kind of my problem, once I played and lost with them, I'd get discouraged and not want to touch them again. But I actually took his advice and played several games with Lucas (I remember telling my brother a few days after Lucas' release how I felt sad that I couldn't really reconnect with Lucas anymore, despite being excited for his return, to the point where I felt like I had to drop him cause I just wasn't winning with him). But after several games of just throwing Lucas into the 'lion's den' basically lol. I started picking up on the playstyle better, doing combos I never thought to do in Brawl haha.
So yeah honestly I think my brother's methods for some things are a bit 'unconventional' to say the least. I'm taking advice from the same guy who literally taunts in the middle of Sudden Death for Pete's Sakes lol. So just throwing a character into For Glory may not really work for everyone and reading guides and watching videos won't necessarily hurt you either. But in my case I'm super lazy haha, so I let myself get destroyed in For Glory and learned my mistakes, how to approach better etc.
For Glory's also unpredictable where some moments I can win several games in a row and then lose several games in a row just as easily. I don't really stay in a room where I know it's an impossible match up so say after three games where I'm on a constant lose streak with said person, I'd state my GGs and leave or something. It's about having fun first off, so I see no need to torture myself and getting stuck in the mindset that I suck by continuously losing against this single player and I must absolutely beat him or else. I have tags like 'Good run!' or praising a person that they're good before I leave since it's not like I'm leaving out of rage or salt. If I can't win, I can't win lol.
Unless of course it was a spammer/campy person then yeah I'd leave salty then without saying much of anything lol. Also this kinda king out way longer than I expected. Whoops.
