I totally get it, trust me. I can see why someone who has based 90% of their time on Asylum playing cop has become frustrated with how banks/feds have declined, resulting in less large combat. However with the constant flux in the Asylum meta I believe this "Dry spell" will be something you have to ride out.
Of course we should all be making suggestions to developer team in hope they answer our prays.
In the mean time, you may have to create the content yourself (playing civ/cartel fights) or adapt to what Cop has become
I'm sure things will change, they always do.
