Frag cannons currently seem to be a perfect 'gank' tool for killing slow/unaware ships with ease. They do massive amounts of damage to both shield and hull , with low ammo count not causing a problem for a 1 or 2 kill gank setup.
I would suggest a modifier on them similar to missiles so they are far less effective against shields and only keep their current power vs the hull; they are just too good all round at the moment.
