Seems like we will be stuck in that spec for all of Legion as well. No more tank/heal/dps specs just pick one.

While Wowheads guide does say the further you are behind in your offspec the easier it will be, it still seems like too much unless you'll be able to do your off specs at the same time as your main spec.

Maintaining off specs is more difficult but not impossible - you'll be very slightly behind on the 2nd spec
What are the going to do about the LFD and such when there's not enough people of certain spec? Offer them an extra chest with gold or something for queuing with off spec? Without a weapon?

Wont matter much in the long run I suppose, I keep complaining yet I keep going back.
