>>37343816I'a is a travelling performer though, despite having a Z-Ring, she wasn't shown to look for battles. Even her training of Popplio didn't involve a traditional training battle but rather getting it to strengthen itself enough through repetition until it could pop Brionne's bubbles in one.
Whereas on the other hand, Lana and Popplio have been shown to be inspired by MR in the double royal episode to want to improve with battles (Popplio learning surf since then on top of that). The plan may have been "CotD uses Oceanic Operetta" but they're also not stupid enough to ignore what earns money and Prima earns too much among the final forms to ignore completely.
