Yes but the point is why should that time and gold have to be spent in some city? You would still have to sacrifice time, heck it could be made so you still have to sacrifice gold, but you wouldn't also have to sacrifice participating in actual combat by being tied down to some city.
It's unrealistic and it's bad for balance.
How is it bad for balance? It is GOOD for balance because it is another restriction to high skills. So we provide paraphernalia for training, what is the result. MORE high level sword fighters. You have yet to prove that this is a desirable thing.The requirement to go to a city to train is what provides part of the singular focus on the activity.
Because according to the game they're leading from the front getting into the thick of combat whereas normal knights sit in the rear echelons and fight only when they have to. The hero description claims the hero increases the CS of his unit because he/she is personally fighting in that battle.
Yet both Hero's and non-heros get wounded in battles, and by watching battles it should be evident that non-hero's can be wounded when very little damage is done to their unit, suggesting that the idea they sit back and do little is not quite accurate.
Its no so much that other knights DON'T participate, as Hero's throw themselves into the absolute worse situations, the riskiest parts of the combat. While this increases the risk to themselves (which is resolved as a chance to die) it doesn't necessarily mean it would impart a chance at greater skill.
