am i missing something or is the scarab(aoe missile artillery ship) really bad!

i was really excited when i got a scarab for the first time, immediately put it in, and i have done a few runs since, and the conclusion is that while it work well,, it suffer from a serious flaw, that is getting xp or kill for crisis/opportunities!

feel like its attack somehow doesnt count as it doing the killing most of the time so the ship barely get any xp, crippling its usefulness!
