I only asked as it is a classic raider tactic and best used with your HA types, though some other horse can pull it off. You can make a dent in the enemy force when they get strung out or separated. Not something that works well against the Mongol types though.

It is much better to try it on the first attack rather than withdraw and sacrifice units that can’t win.

And right the reason for the timer is the sieges but you still have to use it. I suppose it depends on how much you value the force involved.
