I should probably point out that by CBT standards, even if the ELRM Shiva is overweight, it wouldn't be able to fire all of those missiles without seriously overheating itself.
Once again, we run into a serious lack of consequence for overheating.
As far as NARCs go, most assets are too slow and too limited in their battlefield awareness to eliminate the presence of a long-distance NARCer. Give them a drop off at some point would be nice.
