All agendas aside, Gear 5 has been a disaster for the story's quality.
Nika Piece in a nutshell.
At best Gear 5 should've been something that showed up only at the absolute end of the series and maybe without any of that "secret zoan" crap and be something Luffy developed on his own rather than because he's the chosen one, because frankly it makes Luffy feel more like a puppet of fate, and also there's nothing zoan about his fruit since it still functions more like a paramecia or a logia at most.
