While all 4 factions have long-range e-war (ECM, target painting, sensor dampening and weapon disruption), only Gallente, Amarr and Minmatar have for short-range (warp disruption, capacitor warfare and webbing).
And, as Caldari is using self repairing, high-resistance shields, and both of their enemies are using active defense, it seems logical to try something to counter them.
My idea is a high-slot module that reduces the effectiveness of all repair and booster modules, except the XL versions. The catch is the ship using a module like this is also affected: the module while active reduces the effects of all repair and booster modules used on the ship, both local and remote.
Logi drones can be a way to work around this mechanic, even though their effectiveness are also reduced.
