Where in last ages changes does it say that?
This is all I see in age 73 final changes and nothing in age 74.
Paladin Self Spells*- The formula used to calculate success rate will be adjusted to make casting self spells on your allies easier. A WPA vs WPA calculation will still be made which will require Paladins to have WPA but the new formula will make it so that all Kingdom members have an opportunity to receive the self spell bonuses from their Paladins. In other words, a significant increase in the success rate of Paladin spells, although you still need WPA it won't be as significant a part of the formula as previously.
