Say you've got a character who has some stealth work to do. Maybe they've gotta break in to Big Brother, or you need them to overhear that they're adopted. Would you rather have concealment via illusion, or via shapeshifting? Illusions can sometimes be seen through, while shapeshifting will have the limitations of the chosen form. Both would have energy limitations and depend on the stupidity or obliviousness of those being spied on or snuck past.
So, would you rather go all Animorphs with a fly on the wall, or all Dr. Who with the psychic ID card? How would your character pull it off, and would you let them get away with it?
