I think it would be a new toy and lots of tactics could arise from Neuting Smart Bombs and Neuting normal bombs.
So if an anchored fleet got caught by a neuting bomb all would lose cap. Logistics could be targetted by Neut Bombs. Faux could be targetted as these tend to be a bit too overpowered.
With regards to the smart bombs they should come in all sizes right up to capital. The capital ones having nice range. To temper their power they could require high skills and or have terrible fitting.
I also think they should all have a mutiplier effect. So a neut SB or neut Bomb does 1 x effect to frigs 2 x effect to cruisers 3 x effect to BS and so on. This will mix the meta right up and change what is the highest threat on the field of battle.
Ceptors rushing BS groups with neut SBs and so on.
These I my original thoughts and I am sure the delightful people on the forum can add to the idea to make it work.
