None of the varieties (beam, flak or missile) working in any way in their current form. Anyone who wants anti-missile can use pretty much any other weapon more efficiently for the same purpose.
I thought that speeding them up would make them more effective by giving them a sporting chance of shooting incoming missiles down, but I now realise it's a targeting problem.
Are there any plans to modify these?
Perhaps we should brainstorm a little to find some ideas, unless Steve already has a Solution™ to make these useful? Other than that, Hive ships could lose the anti-missile slot in favour of decoys - keeps the same idea but gives something that's actually, you know, usable.
