When do I break out my 80 tank?

I thought they had to be green to the level 80 which is the mobs need to be 74 or something like that.
you can take your level 70-71 to some place where the 80 can kill the mobs and get good xp. the elite worms in NW dragonblight are good and some of the mobs around camps just N-NE of Naxx.
