Any way to randomize movement a bit when fate grinding to prevent so many bot trains from occurring?
If not will a feature be implemented in the future to prevent this or will our only option be to create our own nav-mesh?
You can try General->Randomize Paths , that will make it travel via different paths when not in combat. Combat movement isn't randomized, so you still might run in a line with other bots when inside a fate and attacking the same target.
it still does make a train even if not in fate. i bot 3 accounts for fate grind in groups all have random path but some time it end up in a line on top of each other. So i set evca point far away from each other so they get there in different time and different way like south north east west. but yea if more randomize is better.
