Let me just back up here and make sure I understand...

What does competitive questing have to do with this "chosen one" issue?

Aren't you just annoyed that the player character might end up being the protagonist?

You're controlling a party, not just a character. The point is that companions are mostly under your control, so it's kind of silly to be actively undermining your player character while controlling your companion.

All it would take is for your friend to join your game and you can do all the competing you want.
