Juggling POVs isn't easy, Sadie and Carter usually go on their own little sub-quests so it is easier to juggle POVs between them (not to mention that there are only two of them), the 7 usually go in groups of three on the sub-quests, so if the demigods switched between each other it would be hard to keep track of who's POV you are reading, and that is twice as hard for the writer, imagine writing a bunch of different perspectives on the same sub-quest and you need to remember to switch between characters, you are used to writing from each perspective but you might mess up (Maybe Jason starts acting like Leo). Rick's choice of POV relieves some of that pressure.
