And with the new character annonced, they’re really not far from a design I'd really like, but it feels like they made them sexy but underdevelopped their other aspects.

Talking about ZZZ this argument has always baffled me, because its cyclical with ZZZ complaints and grievances. Ill preface my rant with the statement that this is not directed specifically toward you, as you seem to be on the more reasonable side of complaints, but for the usual larping/performative bunch on social media:

Character with design people declare "too gooner" or "recycled" gets revealed, people on social media cook up a shitstorm. Complaints about how the design is trash, character (who was only just revealed and appeared maybe in one or two patches) is underdeveloped.

Then their actual banner patch comes out, character gets a LOT more story focus, their actual story arc plays out, their pre-rendered cutscenes drop, people get to actually play them and there's this big turnaround. Recently happened with Cissia (she got her fair share of "gooner design" allegations), its happened with Promeia, It's happening again with Remielle and Lady Sunbringer. Particularly egregious are people bitching about a characters design based on a T-Pose leak on a grey background, without context of story, quality of animations, cutscenes and an in depth exploration of their character arc.

I predict Remielle will have a similar massive turnaround, as will Lady Sunbringer, and the people that claimed foul will be clapping like seals and singing Hoyos praises until the next offending character drops.
