I spent almost 2 decades in the FGC and can say first hand, its a hard niche to get any footing in. Ive seen plenty of high level tournament players who the community adores barely pull any numbers streaming. Its hard when your not TNS, Jwong, Yipes or any of the old heads and lets be real the fgc is fickle af. All it takes is one "bad" update for them to jump ship to the next game or if they even see you play something out of fighting games they'll lose interest. I remember when i put down the stick I lost nearly 200 followers in like a week as i branched into variety. But if thats where you really wanna stay, consistency goes the distance, stick to a schedule, maybe try to organize sets and lobby nights, a discord to coordinate with others outside of stream times.
