What Offensive Spell Abilities Can Crit?Follow

Okay, so I'm wondering exactly which abilities a paladin has can crit based on spell crit. I've actually played a paladin, but I haven't paid much attention to what can crit (and at low levels crit% is tiny, so critting is at best infrequent anyways.)

I know judgement of righteousness/crusader can crit, and I'm assuming that judgement of vengeance/blood can as well. Of course, so can exorcism, and I'm assuming hammer of wrath, holy shock (duh), holy wrath, and avenger's shield. Crusader Strike too, I would assume, but I'm not sure if that uses spell crit or melee crit.

But can seal of righteousness/vengeance/blood crit? Can consecration crit? What about holy shield and blessing of sanctuary?

The reason I ask is because I was curious how much a moonkin druid would help out a paladin who was either protection or holy specced. Obviously, the 5% crit would help with getting more crit heals (and therefore more mana back) but I was wondering if it effected any of those other abilities, thereby increasing the paladin's dps, and presumably helping to tank (though not something that should be depended upon, obviously, the extra damage from crits would ease the stress of tanking somewhat, I would think.)

Actually, I have seen consecrate crit.

I must say, I'm highly skeptical. I use Consec about 2-3 times per fight and it has never ever critted for me. I may not have a high spell crit rate, but I've had Hammer of Wrath, Exorcism, Holy Wrath and Judgements crit quite a few times already.

Are you sure you didn't just JotC on one mob and thought it was critting because of the higher numbers? O_o
