If the roll, including modifiers, is between your AC-5 and AC-1 (so that it still misses, but it's close!) the animation of the attacked character should depend on the armour type. Dodge for light, blocking with shield (if equipped) and weapon for heavy armour. Medium can go either way, for example, depending on the character's STR / armour weight ratio. I can easily picture Laezel dodging attacks in her half-plate, but definitely not in anything heavier than that.
