Fullpower95- I agree with you about Frank being slightly underdeveloped compared to the rest of the seven but Piper is developed!!! To me she seems to have grown and become more mature but now I'm starting to think she was always like that... We just couldn't see that in TLH because she was really worried abou her dad. I mean, I can see why some people don't like her because at times in MoA she seems very controlling and posessive towards Jason (who, after reading MoA, is now my least favourite character) but i think that's only because she had heard all about Reyna and didn't want to lose Jason.

IMO It's Jason who seems less developed. In TLH Jason was one of my favourites out of the new characters but now.... I HATE HIM!!!!! - To me he just seems like a faker version of Percy... Oh well.
