If you guys think leveling fishing or FATE grinding a fourth/fifth/sixth battle class to 50 through FATEs could be considered satisfying or interesting content to anybody, then you are seriously delusional.

A new dungeon/raid/primal encounter is content. More stuff to craft is content. A new game mode (PvP) is content. Treasure hunts and dailies (though a bunch of people are gonna hate them) are content. Leveling one of every class to 50 through the same zones, the same FATEs, and the same quests is not additional content, and certainly not the kind that will retain players.
