So it looks like the extra dice for a Divine Smite are rolled twice as well when a critical hit is scored. That's pretty cool, but I've noticed that you don't designate a hit as a Smite until it actually hits. So, even though it is major cheese, it stands to reason that every time my Paladin crits it would make sense to turn it into a Smite. Am I reading the rules wrong? Is this overpowered enough that it requires errata or a house rule? I'm just curious if anyone else has come across this.
