I've never been a Gunman myself and only seen the animations on NPCs, so I'm not sure about something:
Before CR 2.0, I clearly remember my enemies kicking me a few meters back or jumping back themselves and then firing their arm(s); what I don't remember from CR 1.0 but see all the time now is my enemies performing artistic rotations and jumps while shooting off their guns.
Has the first group, indeed, been removed by CR 2.0 and the second one added?
