There is no conversation here if you are going to be dismissing any input without offering an argument. My point is that you don’t need to play alpha to figure how some of the changes will impact tanking in midnight: its either going to be very easy or restrictive.
Restrictive scenarios means that if you want to pug higher keys, you will most likely play the tank that can fit in. If all the healers are losing interrupts and CC remains important, there is a good chance 50% of the tank specs will have to do keys with friends/team or will rot in queue.
