The real reason your sapient dragon character needs a "rider":
- Dragons on the wing are vulnerable to being mobbed by smaller, more agile flyers, particularly in your large rear blind spot, like a bird of prey being mobbed by crows. Having a human armed with a long spear perched on your back helps to dissuade anyone from getting any funny ideas.
- Breath weapons are impressive enough on the ground, but in flight they're really only good for strafing stationary targets; trying to use your breath weapon in an aerial dogfight is a good way to get fire up your nose. A real fight calls for sterner measures – and, concomitantly, a crew to aim and reload the cannons.
- In today's competitive world, it's not enough to devour a flock of sheep and call it a day if you want to keep your edge. You're accompanied at all times by a qualified personal alchemist tasked with carefully regulating your internal furnace to ensure peak performance, and sometimes you even listen to them.
- No dragon of any quality would be caught dead without their valet. It's not as though you can announce your numerous long-winded titles yourself when introductions are called for, can you? You suppose next you'll be expected to pick up the spoils of your conquests yourself, like a common brigand. Perish the thought!

I mean, on leafcutter ants a little tiny one will ride on the leaf carried by a soldier just so she can fend off parasitoids
