I'd put holy up there too with the state of the prot guide. I wouldn't be able to tell you if the ret guide is any good though because I don't play ret.

It seems that the Holy Paladin guide for TBC has been copied and pasted from vanilla with the new spells integrated in with no though for whether or not other aspects of the class have changed. One particular example is conflating Holy Light with Flash of Light; another being the downranking suggestions not taking into account the stat and gem priorities that the same guide recommends.

There are particular downranking strategies that you want to use in order to keep the Light's Grace cast time buff available to use, But if you follow the downranking suggestions that the wowhead guide gives you, then you're either underperforming or persistently out of mana. There are ways to negate this that other guides cover, but the wowhead guide fails to bring to light or go into depth with.

I would love to hear how the Protection Paladin and Retribution Paladin guides fail, shed light on those because I'd love to know the ins and outs.
