So I've been playing an ironman play through on easy which was going fine. I have played the early game a dozen times and can get through Depot A easily (albeit it is on easy). My last game was with a sledgehammer character and I ran into a group of folks that generally in this respective zone(Thick, Dirty Angela, Derailed Mike, Colt and the Animal). They are literally impossible to kill and I got killed by one throwing knife at 350 hit points which i thought to be impossible. I understand this game has strange peaks in difficultly but this was surprising. Will I run into groups like this often, maybe they are not a "rare" spawn, and is playing this game on ironman possible?
