While we're discussing prot paladins, I ran heroic Nexus last night as 5x protadin. Fastest run I've had in there. The AoE spam is absolute craziness. Hammers flying all over the place, everyone dazed all the time due to shields bashing mobs left and right. Very, very fun run. I'm planning to do a few more heroics tonight and see how it goes. I think over the run I was pulling about 4k dps as every pull in there almost is a 4-5 pull. Bosses were slower without the better single-target ret DPS but overall, a very fast and easy run. I imagine I will use the 5-prot setup for just about everything except bosses from here on out. Be interesting to see how it scales in the 81+ instances.
