Riding skills progression is good because you are doing it all the time, if you ride across world map on foot you will increase your athletic skills,not so fast I think, but it's obvious, if we spend so much time doing a particular and ordinary thing, we will be good on it, if you trade all the time you will reach the highest trade level, or if you spend the entire game in a forge, you will be a great blacksmith, and your riding level will be a misery But the balanced player will never reach the highest values of anything besides those that are naturally common due to the essence of the game.
