if you expand this to "fairly easy" instead of just easy, add shades to the list. considering what some of the my org enforcers have said, add fixers as well.
enfo's have an easy time killing shade's in a non duel situation because its fairly straight forward for the enfo to stun / fear or kite to break the SP line. then 1hb perks, sneak attack, conc perks and some regulars do the killing.
