2/5 t13 + the rest cataclysmic
Full pvp, while it certainly feels safer than 2/5 t13, is extremely stiff in that if I get cc-ed out of melee range (which happens often) I can say goodbye to being able to properly heal my DK if she gets nuked. Furthermore, sometimes just getting zealotry up can be hard if the gods of RNG do not favor me and I get parries/dodges on crusader strike. Finally, I don't think the 5% less dmg taken really makes such a huge difference in a triple dps setup, even though it might make me feel safer.
What do you guys think?
