Iv been thinking about this type of hybrid for a very long time, one that stacked shield block and anything with a high amount of strength. As a prot pally who isn't trading avoidance for block (yet) I can hit pretty hard with Shield of Righteousnouss. The person in the following video is using the ideal gear, but he is full Prot.
see that 13k crit at the end? take that value and multiply it by 9% from Vengence, 3% from Sanctified Retribution, 3% from Crusade (6% in most PvP/PvE situations) as well as a 20% stat reduction on theh enemy and you pretty much have a 1 shot spell. Of course this damage would be reduced by a high amount of resil, as well as other spells, but this is still a really high value. It might even be considered a decent PvE spec by some (off tank/dps). Now that dual spec is out however, it pretty much eliminated all hybrid specs, because they are not needed any more. Personally, I enjoyed playing hybrid specs because of the different style of play they offered. This is one of the few specs that I havn't seen, but I am eager to try when I get the correct gear. Any thoughts on if this hybrid would be accepted into PvE? I estimate you could push around 3-4k dps in the right gear.
I'm not seeing how your PvE DPS would be so high. You're missing a basic attack in Hammer of the Righteous. Yes, you would get very high Shield of Righteousness hits, but I don't think it can make up for missing an entire attack.
I'm looking at one of my Prot Pally tank's WWS. HotR contributes 17% of his damage, and SoR contributes 21%. You'd need to almost double the possible SoR damage to make up for the loss of HotR, and I don't think the few extra points in Ret will do that for you.
Personally, I'm not sure that this would work. An extra button to press--to fill up empty space in the rotation is huge--and is a much bigger advantage than extra damage talents. This concept might be fine in PvP, where burst is very important, but it won't be good for sustained PvE DPS and threat.
