Coming in an upcoming patch is the new Faction Upgrade system.
The Faction Upgrade system (I sometimes call it the Great Keep Upgrade system or GKU ) is a set of upgrades that will be available from the citadel.
It will upgrade various things for your faction buildings, heroes or unlock units.
Each faction will have a different set of upgrades but share some core upgrades as well.
Universal Faction Upgrades.
Every faction (except Lorien for the 2 tower upgrades) will have access to these upgrades.
Great Keep Upgrade - Upgrades citadels into Great Keeps which gives them more health and acts as a prereq for Keep Defence and Keep Housing upgrade.
2500 - Tower Fire Arrows (the upgrade is getting moved to the Citadel for all factions)
1000 - Murder Holes - Removes the minimum firing range for towers and improves their armour and range (I'll be adding a minimum firing range for them with this system)
1000 - Keep Defence - Unlocks the Great Keep's "Keep Power"
2000 - Keep Housing - Increases the CPL (counts towards the Expanding CPL counter)
Keep Powers are a unique ability that each citadel gets somewhat like the Fortress powers in BFME2.
