Like the title states, there is no auto attack sound when the attack happens immediately after you Dodge, Parry or Block. Easily reproducible with 1 handed weapon + shield or 2 handed weapons:
- Auto attack target
- Wait until you counter an attack after you Parry, there is no attack sound.
- When the attack happens just after you Dodge no sound either.
- Also happens when you block.
I was able to reproduce this with both Warriors and Paladins.
