I was honestly surprised when I didn't see CEs in 6.0. Such a shame. FATEs are are one of the most boring content there is in the game. You could repurpose dungeon bosses, give them a new paint of colour and synch them with the level of players. That alone would make it way more enjoyable than yet another FATE with the same enemy copied 30 times where all you do is press AoE#1 followed by AoE#2.
