Distibuting Minion

hai…currently i just create an MOBA game, it have some minions.
networking using photon unity and A* Pathfinding by Aron G.

i have problem about minions at attacking. how to distributed them so not overlapping by other.
by the way i have add charactercontroller each other, and i was trying to add capsuleCollider, but they still trigger each other while in position.

Put the minions on a separate Layer and ignore that layer to stop them triggering each other.
