One hit weapons. And general feeling that dying is so much faster now. D2S1 was all about teamshooting, that's true. But thing is, you always had time to react. Power ammo was for snipers, GLs, Shotguns. It was a means of getting that weapon that will instantly one-shot somebody, so it was obvious people would fight over it. Nowadays you have snipers, Mindbender's Ambition and Mountaintop available at the ready. I've been in countless situations where a guy jumps in the air with the sniper, he gets 3 shots from my pulse what causes him flinching, yet I immediately get 1-hit-KO'd crit'd out before I manage to shoot again. How do you counterplay instadeath rofl? I remember being able to take a few hits and run to cover and then try to outmanouver my enemy. Nowadays everyone use snipers/GLs or Shotgun (probably the least annoying one) to one shot you anyway, without need of Power Ammo. This is the greatest killjoy ever, to not be able to do ANYTHING if caught unfortunately.
