Enemy block sounds align with animation instead of blocked hits
I've always felt fighting enemies with high block in OpenMW felt weird and the block sounds seemed delayed, so I did some testing:
Morrowind plays the block sound every time you hit an enemy but the hit is blocked, so the block sound replaces the hit sound.

But OpenMW plays the block sound only once per block animation, seemingly at a specific point not dependant on the blocked hits. All those swings here are hits, but silent because they were blocked without a sound.
