I will say I've seen some pretty crazy numbers on the ptr just tonight while attempting to test ret in PvP and failing miserably I decided to see just how much damage the class is really capable of so I paid a visit to a dummy in my PvP set and was rather surprised to see my first templar's verdict did a total of 683k.
Now while this is in fact on a dummy you can imagine just how painful that would be in PvP with 31% pvpP on top of that after resil and to top it off this was with no outside buffs simply normal cool downs and might.
For those looking to try this I use t15 4pc with tyrant head and my gems of choice are str/mastery, pure mastery, and mastery/pvpP as well reforging mastery > crit > haste.
