But we already do have some FATEs that are not fixed to location but spawn in a random location. Granted, they're only the most 'elite' FATEs, but they still spawn in random places on the map: Odin's FATE 'Steel Reign' can spawn anywhere in the Black Shroud so it can even spawn anywhere in multiple zones, Coerulregina's FATE line can spawn randomly in several places in the Dravanian Forelands, The Protoultima-connected FATE 'Prey Online' likewise has multiple potential spawnpoints in Azys Lla, etc etc. Of course again these are only elite FATEs and not your run-of-the-mill 'kill bunch of enemies before time runs out' style trashmob FATEs usually seen, but they are still what you are after. Maybe SE could actually make more FATEs like that.
