I would argue :
Dark Matter Field:
Bonus to maximum velocity
Penalty to turret range Minmatar Munin/Broadsword
Plasma Firestorm:
Bonus to armor HP
Penalty to thermal resistance Gallente Deimos Phobos
Exotic Particle Storm:
Bonus to scan resolution
Penalty to kinetic resistance Vedmak (future t2 vedmak?)
Or maybe the Vedmak Battleship will end up ruling the day here
Electrical Storm:
Bonus to capacitor recharge
Penalty to EM resistance Amarr Zealot/Devoter
Gamma-Ray Afterglow:
Bonus to shield HP
Penalty to explosive resistance Caldari Eagle/Onyx
I believe the heavy interdictors are meant to be the lvl 5 heavy hitters and that ther’s no shortcuts, we have to know how to Fly the ships… not just how to fit them, and that if the appropriate ship is flown properly it will be the best suited for its environment
