"they are quite expensive and very useless outside of that role."
"Screamers (great for tank-hunting, but expensive and worthless otherwise)"


You just said they were expensive now you say they are cheap, what is your view on them? Your comparing apples to oranges when you compare them to other units. Screamers are exactly as described jetbikes with meltabombs stapled to their heads. They have the fastest movement the demons have and the most reliable way to blow up a vehicle and they can make a person with tanks think twice about hiding back behind cover giving up their movement.
