Gonna shill my brilliant idea again.

Royal Authority putting a buff on the paladin that lowers the next spell cast by 1-1.5s...makes Clemency better, and opens an avenue for adding new paladin spells in the future that we'd make viable through the spell cast reduction. Maybe get traits that let us stack the effect later on. Instant clemency after two runs through the rotation, or used to make, say a high damage spell named Banish, go from 5 seconds to 2 second cast time...

Would give paladins a unique "style" both to their stabby side and their casting side.
