Assassination missions where almost impossible to beat for me when I started playing a few weeks back, especially when Anacondas or Pythons where involved. Now I'm in a fairly well upgraded Vulture and the game pretty much turned into a cakewalk. Anacondas or Pythons sometimes don't even take shots at me and I'm pretty much free to just blow up their reactor (I usually target that subsystem against these two shiptypes). I wonder if that's a bug or if taking shots at the reactor incapacitates them to a such a degree that they can't fire back. The only challenge I can still find is in conflict zones where the enemies are suprisingly well equiped and act much more competently.
