You're absolutely right. They are a bit squishy but they are a "deal eith me now" threat. Again, they aren't THE plan. They are my distraction unit. If you don't deal with them, they are going to hurt you really badly. Lots of shots + lots of attacks and can threaten anything I'd see on the table. The real strength comes from the Nightspinners. Being able to threaten 48" without LOS and have a boatload of shots that cause 2 dam each. Lots of fun there.
