I was recently alerted to the presence of the Hammer of Righteous Might, a 2h mace with a good chunk of spell damage on it. It was introduced in patch 2.3, I think.
So, 2 Primal Nethers, 6 Primal Mights and 28 bars of metal later I had a new toy! What do to with my new 2 handers? How about tank some raid bosses to a pulse-pumping soundtrack? IN THE NAME OF KITTEN JUSTICE!
PS - I see a lot of people in the comments wondering what the point of 2h tanking is. The reason: because I wanted to!
Here's the gear/spec I used for this video. Didn't really do anything besides equip the 2h.
