About 2 weeks ago, I was in HoF LFR. before Grand Emp, our tank left. when after 5 minutes no new tank appeared, I swapped to defensive stance, equipped a 429 1H and a shield I had in my bags, and offtanked as arms, taunting when the other tank had 4 stacks. I died 3 times and got rezzed 2 times, took many crits and was close to death a few times, but we oneshot the boss. keep in mind I didn't even overgear it, I had 1/3 463, 1/3 476, 1/6 450 and 1/6 483.
is LFR really that easy that a tank spec is nearly optional?
