Another suggestion is to make the CS of any infused spell equivalent to your level if you were single trained in the spell circle.
I think most paladins will agree that minor spiritual is an under utilized spell circle in regards to the offensive spells due to the spell hindrance and lower CS of the spells because until post cap most paladin's aren't training past 120 and even then still might not train past 120 because of DF Redux.
Sure we have champion's might, but this cap's out at +25 and at level 80 I'm starting to notice a little difficulty warding like level foes (I'm trained up to 1640).
As I gaze over the horizon, the wind tugs at my cloak and whispers, "Adventure" in my ear.
