I had this crazy idea for a Paladin DPS build. I don't think it would be topping DPS charts, but it might be interesting to try out. The only problem is that I don't have a Holy-geared level 85 Paladin.
The idea, as you've probably figured out, is to spam Exorcism and use Judgement on cooldown. My inspiration for this build came from leveling my (currently) level 69 Paladin and having my Exorcisms hitting so damn hard. With Art of War, it's just retarded, sometimes 1-shotting mobs. Without it, it's still pretty crazy. The only problem is that spamming it runs down my mana really fast, but that got me to thinking, what if I had more mana? So much mana that going OOM would take a long time? Holy gear! Massive intellect stacking plus attack power buffs would end up giving a whole lot of spell power for Exorcism to scale with, even though the scaling is kinda shitty. Here's the spec I've come up with:

Again, it's probably not going to be a very good build, but I think it could be really fun, especially doing Heroics with it.
