Ottoman Extensive Fortification bonus vizier point works halfly it gives bonus damage to garrisoned units but it doesnt make defensive buildings cheaper also one bonus is missing at the info of this bonus.
By the way i like the diffrenet icons at economy upgrades it can be done to the blacksmith too.
I didnt like the bonus range to archers at university was it necessary?
Elite army tactics at university is good now every footsoldier gets +4 melee armor but its gold cost is too much.
