Did you noticed what Enveloping weapon does to missiles and fighters ? Devours 4 per hit. It seems Env really does not causes damage from all sides when hit, but hits from each side. Accordingly, single Env+AF wipes 12 targets per shot, just tested it.

Maybe, this needs to be fixed ?..
If AI could take such mods, maybe it would be good to enable AF on Fusion Beam, but as it is, it seems to be useless.
