I think they brought up p5 specifically because it's a super-modern turn based RPG, so the same kind of thing a new, turn based, ff would be. This modern game, despite being overall well received, got some criticism for its turn based system being too much of the "use obvious elemental weakness" style strategy, and not more novel ideas.

Ooooooooh. Ouch. “It is a series standard” is exactly the sort of weak point that leads to some big franchises like Final Fantasy staggering.

There’s a reason games like Persona gained such popularity. It is NOT because players learned to use a thunder attack on the floating pair of chairs.
