Yeah, I've used a holy priest before while leveling, it was cake. Then they nerfed circle of lol into the ground...and it was still cake.

Back in the day when dinosaurs roamed the Earth and men were men, Paladins needed all sorts of stats. Pretty much everything, you name it, including spell power. As a result, gearing them up was just retarded, and the only really viable spec endgame was Holy healers. One day, Blizzard came down from on high and said "hey ya'll, this sucks, have some better itemization"...and ever since, only Holy Paladins still care about spell power. Everyone else gets it incidentally from other stats. For example, look at the formula for Consecration - [8 * (113 + 0.04 * SPH + 0.04 * AP)] - all you need comes from attack power. You can have spell power, and it will do stuff, but it's by far the worst way to gear your non-holy Paladin as you will get the same effect from other stats, and those other stats will also make your melee strikes hit like the fist of an angry god.
