The Warrior Temple only grants +1 to the starting level of trained units and +2 to the initiative of city defenders, whereas the War College grants +2 and +4 respectively. In addition to this, the War College also grants the Enmity trait to trained units. This makes the Warrior Temple look like a weak copy, while having the same build-cost as the College. Correcting the above values and maybe granting the Bloodthirsty traits would help balance this out.
