I'm fairly new to prot paladins, but lately I've been noticing alot of tanks using Hammer of the Righteous on single target bosses, like Cho gall and Ragnaros.
One of the best geared tanks on my server is a paladin and he keeps using HOR more than CS when hitting one target. I thought the general rotation was that you use Crusader Strike on single target fights and HOR when hitting multiple mobs, or have I missed something here:P ?
