Fixed ^^Purify: This is your first debuff-removing spell, you get it long before cleanse.
Turn Evil: 99.5% useless, but, ti's fear. But, they run around all "ahhh ahhhhhhhh", so, it's fun.
Hand of Protection: You can cast this on other people if they're taking physical damage. Also good for annoying a hunter when they pop CD's.
Hand of Sacrifice: You can cast this on other people if they're taking damage. Good for helping transfer damage off a tank during a boss XYZ Facesmush ability.
Hand of Salvation: Reduces someone else's threat. Good for when someone (somehow) manages to climb the threat meter like a dog in heat. *cough* Feral Kittys.
Righteous Defense: It taunts three mobs, it's a secondary/backup/situational taunt. Also, Avenger's Shield is a poor means of generating threat outside the initial pull.
Seal of Justice: All around crap, with extra crap, on a crap burger.
Divine Protection: Paladin version of Shield Wall, reduces all incoming damage without making you immune to damage (aka the mob doesn't run off and hit that damned hunter who won't FD)
All in all, you may want to brush up on your Rogue.
