I did have to hang back a little on Hardcore here, which is really not easy at all die to the complete lack of DBNO when playing solo(well, I did get down once but that was at the train station in Act 5 when I was too close to an opening grub hole but I didn't die to it), and stuck to my Lancer&Longshot combo for the most part with some use of the Boltok when a helmeted Locust survived a headshot. So I was wondering whether I should stick to that as well or if I should change the Longshot for a Boomshot or Hammerburst. I did sometimes use a Torque Bow but that was when I knew it was safe to take it and I could retrieve my sniper at the same spot. Or when it came to killing RAAM. Was surprisingly easy, though I did die a few times before I managed to kill him because he got stuck due to Dom running into him and getting stuck because he tried going forward but it didn't work as Dom was downed and blocked the path. At least for once he was some kind of use.
Also, for anyone who's played through Insane, how many Longshot headshots do Therons sponge now? Three was already bad enough, they took almost as much fire as a Boomer(same number of headshots in fact, except that Therons would die to a few Lancer shots after two headshots).
And do snipers kill you with one shot? What about Boltoks?
Any advice or tips are appreciated. Do I need to be even more careful?
