Hmm... I'm not sure I agree. What about FFX? If you level up enough you could kill just about anything in 1 hit. Even the final bosses!

EDIT: But how DID you do that, right before the Temple of Ancients, I have all my characters over Level 45, I have all the materias available to this point Mastered (with exception of Kjata), and I even have 2 Mastered HP PLUS's! And I still can't reach 9999 HP with more than 1 character!
