ECM always was a caldari themed weapon. Their main enemies, gallente, are drone nation.
So I suggest that curent change of how ECM works will have one small feature: if you apply ECM on enemy ship, it can target you, but his drones can’t.
Enemy ship still can fire guns, missiles, whatever desintegrator it has, but his drones will not harm you as long as your ECM is applyed on that enemy ship.
Make ECM anti-drone weapon!
