Only valid if you think he'll make a good provincial governor as dread has no effect in battle.

Just me two cents.
IIRC RTW/M2TW's AI also does not retrain it's units. This has not yet been implimented in a TW game as far as I'm aware.

Generally, if you want to do the AI a favour and you have just won a battle, routing and capturing hundreds of low quality units from the enemy... hit the button. If you've captured mostly half decent troops and the AI's economy is solid, then ransoming is the best option.
