If you look at the various special weapon types (Phaser Blast, Incendiary Blast, AP Incendiary Blast, Laser, etc.), there are multiple units that use them, and all of them are used by a recently released unit.
Volley Blast weapons, though, were only ever used on the Steel Rain and haven't made an appearance since. I find it particularly interesting that the Rocket Pods, 250 kg Bombs, and Napalm on the SSU Ground Attack Helicopters don't use the Volley Blast mechanic when they would seem to be prime candidates for it.
So, do you think that the designers consider Volley Blast to have been a bad idea? Meaning that we will probably not see any more units that use it?
