With all the talk of tanks and DPS and all, I had a random thought. Do we really need an off-tank? Yes, some battles require tank-swaps, and a small number of times you need to tank two things apart (Bismark), but in truth 99% of the time an OT is just locked in DPS stance, DPSing. Now, there are a shortage of tanks, and we all know how bad DPS queues are. So I was wondering, what if SE designed future 8-man content to instead require one tank, two healers and five DPS? Not only would this help even out queue times, it would avoid sticking a tank in the role of second-hand DPS. Yes, you would lose tank swaps and mechanics like Twin Bolt, but would that really be so great a loss?

Like I said, just a random thought that came to me.
