I dont do a lot of pvp, but this week I had to get 50 HK's for the holiday meta. I did a simple Hammer, Word of Glory macro and with 54k hp, 680ish resiliance and swinging the mana/heal seal I didnt do much in the way of DPS, but holy crap I was retarded hard to kill. In one Eye of Eternity bg I had 2 deaths and over 70 HK's. It did take 8 or more to take me down.

Course my guess is most of the other people there were not pvp experts either, just going for the meta.
