the bot basically attacks the closest mob that meets the current criteria. so in fates you will see this happen alot when mobs spawns everyone hits the same mob. basically though this happens alot when playing by hand. people spamming tab or auto target on attack so the first mob to spawn everyone targets. I honestly think you are overthinking it.(especially in fates) Randomize movements is a setting for melee characters to move around the target slightly randomly.
