Dual-wielding attack speed slower than intended

When using dual maces, with the same attack speed on both, skills which does not have an attack speed penalty while dual-wielding, such as sunder, is attacking slower than using a single mace, as shown in the video below. Dual-wielding is considerable slower.

This happens with every single skill, only sunder is shown above to showcase the point. I noticed the same behavior on Rolling Slam and Boneshatter, where both does not have an attack speed penalty.


Also, skills which have a attack speed penalty, such as Volcanic Fissure, appears to be much slower than 30%, shown in the video below:

Based on what I know, dual-wielding does not have a attack speed penalty, so it appears to be a bug.

If I missed something, please let me know. Thanks!

Same issues man this stuff is driving me crazy and making my build less more enjoyable to play may have to drop dual wielding 2 hand maces becouse of that
