The characters who I think with the worst development in HoO are, surprise surprise, Percy and Annabeth. It's not that I hate them; they're actually personal favourites of mine, but I think HoO didn't expand on their development from the original series (which for a children's series, did it better). For one, Percy turned out "too perfect", in the same way that people say Jason is. Others might disagree, but looking back, I felt that Percy became less relatable over the course of the series. Maybe it was inevitable because Percy had to grow up sooner or later, but he seemed more of a "legend than an actual person" in the words of Hazel Levesque.

Annabeth, on the other hand, lost some of her "Annabethness". What I mean is that she became too occupied with her love for Percy, and forgot about the greater good. Sure, her boyfriend was taken from her for months, but someone as mature as Annabeth would've put it aside until the war with the giants. I'm not saying Annabeth isn't allowed to process her feelings like other people, I just thought she would've focused more on the war than her love life. It might be a biased because I prefer little-to-no romance in my books, but I still stand by my opinion that Percabeth was made too much of a deal than it should've been in HoO.

I'm not saying Piper and Jason are any better, but these are just my two cents on the matter. May the trash throwing begin.
