The player's choice in how to defend changes what the DM narrates as the situation after in DW.I'm still trying to grasp the concept of this;
Over, "Roll for the monster to hit you, it has +5 to hit."
Or, DM rolls and misses the AC by one and says, "You raise your shield at the last minute and the blow slides off." Or, DM rolls and misses by 5 and the says "You sidestep his clumsy attack and prepare to counter."
I guess my big problem is that I do not see where this will make things faster/easier/funner?
Fiction driving mechanics instead of mechanics driving fiction.
