also use the upgrade path wisely and build upgrades tailored to that line of units.

this was discussed on a thread some time back but

armor for spears and then morale, weapons etc. woudl come last.

morale may have to come first if spear is 0 morale

same for archers and missiles with armor, morale, weapon last.

exception is HA where they need morale more than armor as skirmishing around, they suffer from the constant retreat penalty and the worse thing is to have them rout off the field.

the attacking units like m@a and knights shoudl go for weapons and then armor as they need to shock and break the enemy line and survivability is also nice but they need morale least as they usually have decent if not very good morale to start with.

it may be good to have a province with valor go straight for building the master level building and retrain elsewhere for appropriate upgrades.
