I've done some thinking on it - would it become imbalanced if worldhopping was random? Like, if you're on Roshar C1 (and we have more than 18 players, so we're using all of the world docs), you have a 20% chance of staying on Roshar for C2, and a 20% chance of going to each other world doc. Maybe instead of that, worldhopping has a 25% chance of failing and landing you on a planet that isn't where you wanted to go.
