Man, I'm surprised there's still hackers abound. Figured that with the general playerbase shrinking, these people would move on and get their jollies from elsewhere.
Stumbled upon some guy earlier while farming the DZ for loot for a level 24 alt,
and as I'm about to extract he just appears out of nowhere and oneshots me with an SMG, first bullet and I'm down. Respawn, sneak back, I plant a sticky bomb right into him and detonate. Now at that point it was oneshotting lvl 24 purples in there, so I figured he'd get minced. His healthbar doesn't even move a pixel. Then I see he's DZ level 67 with a 24 character. Given the DZ levelling curve, he can only have been going rogue all the time to gain enough exp for that.
Oh well, I left that instance. No point dealing with such folks.
