At the moment attacks with splash damage (think of level 3 mortar, bushcricket bleed) have no hard cap on the damage they can do. For leafcutters a fight against multiple large bushcrickets is very costly and gets disproportionately more costly for each additional bushcricket added. With bleed it would feel more logical if the bleed per ant would be less the more ants in the fight. As the more ants there are, the less each individual ant is exposed. For mortar ants the acid spray only has a certain amount of acid. the more ants in range, the less acid there is per ant.
The general idea here is an upper limit to the amount of damage area attacks can do. And if there are enough enemies in its area of effect that it would exceed the cap, the max damage get's divided by the number of enemies in range before being applied to them all.
