Yup. It's why I've been pushing for the Assault profile instead.
See your point. Yes just changing them to assault 2 would be something.
Honestly, it would be better served as a terrain piece of some sort--or benefit from having Master of Ordnances on the field or something. There's a lot that can be done to make it work(because if we go with 'realistics' for stuff, we shouldn't see named characters yadda yadda yadda).
They remain a fun thing to take for big games. There are multiple ways to have them count for more, but really you are taking one, saving the CP
for when it fires and using CP
to try and make it fire earlier.
