Parson's Klog #4:

Stacks without a leader are forced to autoattack when in contact with units from non-allied capitals. I don't know how melee works without a Warlord in the group. With a Warlord, the fight can be directed, or the group can choose not to initiate a fight.
The implication I get is that engagement follows some mechanical rule (possibly random, possibly some preset sequence) without a warlord, and that a fight cannot be "directed" to prioritize specific targets (other than what the mechanics dictate) without a warlord.
