I have a feeling there's a difference between Holy as an offensive spell type and Holy as a healing spell type. You wouldn't think so, considering Holy Shock, and Prism, but it might have something to do with the intent, chant, or thoughts while casting or invoking the spell.
Still, Consecrated Ground and a few other Prot/Ret talents would be great for Holy. I know we're a while away from the Beta and more definite numbers tuning, but just because stuff like Stoicism and DP are okay on paper, doesn't mean to say they'll work out in game, and in fact there are quite a few boring talents.
Even shuffling talents around (with a different philosophy in mind) like so:
...won't help much more, even if there is (arguably) a better comparison between talents, because we're still stuck with stuff that just isn't exciting. Passives don't have to be boring, but with Paladins especially, they seem to be.
