You're not wrong, but you're not right either, it's not a black and white argument. Whilst I can accept your view that good balance can increase character exposure and make a game more interesting, I personally find it much more hype to see a low-tier character battle their way up to the top. In a recent 3S SBO qualifier, the top 4 had Sugiyama's Necro and Hige's Ibuki up there with Haitani's Makoto and Nuki's Chun. That was insanely hype for the exact reason I'm talking about. Same with SBO3 when Kuroda and Hayao took Q and Hugo to the semis.
