The Whole World Should Be Endgame!
Its still better than the alternative like ALL the other MMOs do where you NEVER play with your friends until endgame.
Besides knowing there is a chance for gear to drop of your level is still there and it does happen. I don’t know I have been pretty happy w/ it so far and I have gone back to zones 30-40 levels below where I am for friends.
I do think there is some room for them to make rewards from the rest of the world a little bit more attractive at level 80. On the other hand there might be a danger that the more challenging level 80 content gets completely ignored.
