Well what did Piper do? Let's count on our fingers. Did she stop Percy and Jason from fighting? Actually she couldn't, she had to convince BlackJack to hit Percy in the head otherwise he would have killed Jason.

Did she stop the Eidolons? Not really, she took them out of their bodies but she wasn't smart enough to tell them to leave them be and thus they came back a few chapters later in order to kill Leo, Hazel and Frank.

Her conversations with Hercules and Mr.B? Anyone with just a tad of common sense (which both Percy and Jason don't have) could have handled it.

The only thing Piper did was to get that horn of plently and then use it to have a picnic with Jason and then save them from the nymphs with love.

Percy, Jason and Frank felt more useless? Let's not exaggerate.
