Had a few people ask me to test these again during stream and we are just coming up with zilch. Willow Cap does nothing regardless of configuration, weight of equip load or percentages.
Agility ring does improve movement speed and attack/sprint stamina cost but attack speed never increases.
Agility ring also does not improve weight specific dodges for me. Fast, Normal and Heavy all have the same speed and recovery with any ring configuration both Agility and Willow.
Safe to say I’m done testing these rings until the Devs make note of changes in a patch or someone can verify through video how these actually work if for some reason they require more than the rings themselves.
