A few smart dretches have no problems taking down even a good lucy humie.
Use walls, jump at the right moments and go in waves of 2.
You will die but so will the humans.
And no worries about feeding there since the humies have s3 already.
Also, like someone mentioned above, the guy has more money invested in his gear then a bsuit/chain.
He'll have to be a complete moron not to do any damage or at least kill a dozen of dretches before his death.
