Generally speaking, you are looking for high mobility abilities. The shots they fire are very slow to move, and very slow to turn. Off the top of my head:
- Leap for barbarians.
- Vault or Smoke Screen for Demon Hunters.
- Thunderclap rune for Monks can work well.
- Teleport for wizards.
- ???Spirit Walk for Witch Doctors (I haven't played one or with one at all).
In particular, the teleport style spells can work really well if you move directly to the other side of the ball. By the time it turns around to get to you it will have disappeared.
For melee classes, it works best if you kill off other stuff first, avoiding the bullets. If you can avoid the bullets successfully, the succubi don't do much damage themselves while you're under their effect. The bullets are near impossible to dodge at melee range. If you find you can't successfully dodge them, save your defensive cooldowns for when you get hit and try to smash them down first before trying to work through other things, but seeing as they are flying creatures they can be a pain to keep down in one place with other mobs in the area.
