Friendly reminder that Game Freak seems to think that part of "catching them all" involves trying to use all of them on your team. This is the official reason for both the Gen V experience mechanic shift as well as the upgraded EXP. Share in X and Y: the devs assumed that you'd be using dozens of different Pokemon over the course of your journey, switching out most of them with each new area like an N wannabe.Not that anyone actually uses more than 10 Pokemon per run.
