Swarm also deals poison damage so it doesn't get affected by target's resists. Which allows it to deal more damage than vines occasionally on bosses.
Also, Yrck, looking at your list(nice work), I noticed you said close range melee cannot hit with rooted mobs without being hit with autos. This is true in most cases, however, it is possible to hit the mobs with spear while it is being rooted without being hit by auto attacks. This is because spears have slightly larger range than other close range weapons.
