One PoV would be enough to cover evertything, in MoA I felt like that most of the time two out of four PoVs were useless. Also, I kind of doubt RR will write Percy's PoV again in this book and since MoA was filled with Greek PoVs I'm sure that the most obvious choices will be Jason, Frank and Hazel (which will kill me because they're kind of boring).

Plus, the war back home is just as important and one of the reasons PJO was so great it's because of demigods fighting and working against demigods. Now in HoO it just feels like the all the villains are idiots who get beaten way too quickly.
