1v1 FG is literally random. Theres no ranking system far as i can tell. I bounce between spammy ****ers, total idiots in general, and OMGWTFPWNBBQ strong lol.
You just have to keep at it, do some friend battles with people on here, you get better quick. I think i started off with a ~25% winrate or so, but 3 days later i was up to 60%.
Bulk of it was learning how to deal with troll players. People that do nothing but spam projectiles, sideb little macs, counters, etc. Once you learn how to counter those kinds of people, you start having the opposite problem you have. Now i almost never find a match thats at MY level because its all spammy noobs and theyre super easy to counter for me now.
Chin up and keep going is about all i can say. Watch replays of yourself, dont let yourself do the same thing every time (ive noticed i have a bad habit of trying to dashattack a LOT, trying to work on that). You'll get there eventually.
If youre interested heres a
video of me (green lucario) facing another lucario. This is an actual fight, and i had a blast in it. Not professional level but theres a lot of good movements in there if interested. You can also look up tournament players, theres a bunch on youtube already.
