problem is, basickly rank 400 = dammage cap 1000 vs 250.000 to 300.000 hull
here the Darmos drone, but basickly the same with all the bralkir ships both the LM version and the 2 you can summon with the Vortov

300.000 hull vs a 1000 dammage pr hit cap = 300 cliks to kill (and 250 clicks for the bralkir)
300 clicks = 1.500 energy pr kill for Darmos drones and 250 clicks = 1.250 energy pr kill for the Bralkir
I have no problem with the energy required to kill these ships, but please 250 / 300 clicks pr kill is just a bit pointless

(and for the legion missions you have to find and kill 30 of them = 30 * 300 = 9.000 clicks)
my sugestion is simply this
increase the ranks of these NPC's to rank 2000 = a 5.000 dammage pr hit cap
and at the same time increase the energy cost to attack them to 25 energy pr attack

that way, you would still have to spendt 1.250 / 1.500 energy to kill them if you can hit the cap
but the number of clicks you would need to do would be reduced to 50 / 60 clicks for the kill
