The "do the fates around you to make it pop" is not a solution, I've done that with animus fates and had r same fates respawn a lot.
Also some zones that isn't even viable, Coerthas prime example, clearing fates around the zone knowing how large it is means you can easily miss the one you need.
"Taste of fear" fate I was waiting over three hours and zero spawns, yet all the others spawned tons, svara had fallen so much that I'm surprised she bothered getting back up
They need to change the respawn conditions as currently it is a nightmare, why tie animus to fates if they are on a long cool down

One suggestion would be to make them like the beastmen or crystal tower or Hildibrand zombie fate, have them on a forced timer of say 15-30 mins
