I would like to see the militia event deleted from the game, its unnecessary micro, as it becomes a case of how can I kill those militia as fast as possible.
If its meant to be a 'lucky' event replace them with heavy infantry or archers or something more useful.
I have had 500+ of the little cowardly chaff draining my treasury before now...
There is a number of times when the militia events are good, particualiry at the beginning of the game. You can use them for:
patrolling
defenders in castle
sieging
decorations for enemy knights lance tips
It is when you get a large number of thos eevents that they become a problem.
