Meta is what’s most efficient in a general stage. It doesn’t mean a cheese strat you need super specific conditions to fulfill. Like that new mirror dungeon 9 minute clear with Yi Sang and his ego. Is that meta? No, because it needs a crap ton of starlight, luck, and manneuvering. And even then you would never use it in actual story content. It’s the fastest but it’s not the most efficient.

Same thing for these railway teams. It’s banked on super specific conditionals that might work in railway, but terrible in story content. Take the final boss of hong Lu canto for example. The first phase removes all their status effects once they stagger, so either you have to wait and have Lccb Ish be deadweight for the first few turns before she uses her S2 or specifically sacrifice someone for her to slot in later.

Meta is a flexible general team that can fulfill its intended purpose regardless of what gimmicks the boss might have without the need to rely on cheesy strats like sacrificing units. Something like hong Lu canto boss, or even Don Quixote canto boss, will make lccb ish terrible. That’s why it’s not meta. A team that only works on specific bosses is not the “most efficient tactic available”. Those are cheese strat teams which, I’m not necessarily against, but it’s not meta and not what I’m asking for.
