I don't know if any of you have played any of the Civilisation games, but those who have will no doubt be familiar with its Upgrade Unit function.
That is to say, perhaps you'd been training archers and suddenly gained access to longbowmen. Instead of disbanding those experienced archers, you pay a bit of cash to see them upgraded to longbowmen.
I think the same idea would work well for TW games. Who hated disbanding their gold Chevroned mailed knights because they were outclassed by the Feudal Knights? Wouldn't you rather have simply upgraded them?
