I'm sure I'm not the only one who's witnessed this phenomenon. You're waiting for a Fate, whether it's for marks or Animus, and it never seems to show up. However, that other fate in the area seems to have spawned a total of 10 times while you're waiting. In a Row.

I think this is one of the biggest issues I have with the system currently. Some fates seem to spawn more regularly than others, to the extremes where you're literally waiting for HOURS to complete a single Fate. Waiting for a Fate is not interesting. You can't zone because there's no way to keep tabs on when the Fate will show up. There's rarely much to do in said zone, even if you're doing marks, especially now that they've made B-rank marks provide no rewards.

The solution is pretty obvious. Set a 5 minute timer on Fates before they can respawn. It's not too long that it prevents people actually doing them, but it's also long enough that other Fates can spawn in the time they're down. It might just add enough variety to Fate spawns so that people can actually complete content rather than wasting hours just standing around.
