My AI with regards to walking or finding the player, is pretty much just set up so the payer is the “move to” target, so they will keep trying to get to the player. Their sort of circling behavior is actually more a happy side effect of using the RVO Avoidance on the enemy pawn Movement Component. When you enable that, they will know about each other and try walk around each other. Without that, they just pile up. So because of that they seem to circle you for attack, but really, they just try get past each other to get to their goal, the player.
