I think what they went was: will we describe attacks and you describe the results or will we describe the whole attach and reaction from the npc

basically "I shoot my bolter at the thrall, aiming for its stupid face" vs "I blast the thrall to bloody gibs with my bolter"

the first gives you control over how successful we are where so we don't just godmode our way through everything but the latter lets us be way more descriptive in our combat maneuver because we know what we are doing will work but you have to rely on us self limiting our success.
you probably knew this already so I apologize if this sounded patronizing.
