ECM as a mechanic while not broken or underpowered is simply not fun gameplay by most peoples standards.
if over a decade and a half isn’t enough evidence then the current messy change shows its not something that can really be fixed. Sensor damps are already the best balance you could get for ECM. the idea of a new type of e-war is also problematic as anything not covered is almost if not more difficult to balance than the current system.
so why not remove offensive E-war from caldari and give them a supportive ship.
it can be done in one of two ways
T1 skill gives a bonus to a much needed remote guidance computer
t2 skill gives a bonus to remote tracking computers
t1 skill gives a bonus to all remote weapon enhancers (including adding RGC)
t2 skill gives a bonus to sensor boosters
some logi already give boosts to these but they are hardly ever used as those ships have a more important use for their fitting space.
the reason T2 would give the sensor boost bonus is simply because I see it as a stronger mod.
with this we will not only have dedicated E-war ships but a dedicated ant-ewar ship
