Love the blog! Keep up the great work. Was just wondering though...I noticed you have Imp Right Fury. Does this only apply to offensive holy spells for the increased threat or to healing spells as well? Did you just grab that for soloing? Im guessing you don't have this up while healing correct?
Righteous Fury does apply to healing spells. However, paladin heals are innately lower threat (50%) compared to priest, druids, or shaman heals. And because we run with at least three paladins, I always have Salvation on.
A paladin will have 0.5*0.7*1.9 = 67% threat. A priest with Silent Resolve would have 0.8*0.7 = 56% threat. So you have a bit more threat, but not that much more. Plus, I find it's better to be higher than the other healers on the threat meters. That way, if an add does get loose, it comes to you rather than the priest. With plate and Imp RF, you can take a couple of hits.
Keeping Imp RF on gives you 6% damage reduction all the time, which helps with splash damage. Salvation will "muffle" the effects of Imp RF. So you can keep RF up pretty much all the time in raids if you have Salvation. If you don't have Salvation, you should probably turn RF off.
If you need to watch threat, or if you don't take any splash damage, you can always turn RF off. For example, Nightbane is a fight I wouldn't run with RF, because when Nightbane lands, threat can get tricky, and I don't want to pull aggro and wipe the raid.
As well, it's useful when soloing or doing PvP, and it helps me to tank 5-mans without needing to respec. In the end, there's not a lot of better choices for those 3 talent points. I could drop Imp RF and Blessed Life and pick up Imp Might, but other than that, I don't think there's any other talents that would be more useful.
One last caveat, if you melee to keep Judgements up and you use RF, use Seal of the Crusader rather than Seal of Righteousness. You don't want extra threat from the Holy damage of Righteousness. You probably won't pull aggro, but better safe than sorry. For example, I keep Judgement of Light up on Void Reaver, so I put up Righteous Fury to help mitigate the pounding and run SotC. SotC also has the advantage of speeding up your swings, so you can spend more time healing.
