Attack-move units getting stuck

[NecroVirus]

So in my map two opposing castle spawn units that attack-move to the other side. However they keep bunching up and they will stop moving, or form a conga line that inches forward. I haven't seen this in games like Castle Fight. Anyone know a solution besides setting collision to 0?

In this picture all but the units in frontline stand still and just change their angle to enemy units. How can I make the combat more fluid?

This problem occurs when a player has 100+ units.

Solution: Distribute the units among different owners. Multiple computer players should do the trick.
