Stealth nerf on mace's attack speed - intentional or a bug?

As title suggest, comparing to 0.3, mace's animation/attack speed have been significantly reduced WITHOUT any explanations anywhere.

I believe this is a bug, but it can also be an intentional nerf. Please indicate clearly.

bump, +1, can confirm - just tested on standard with toon from abyss league and compared to old footage, for example earthshatter on dualwield now is significantly slower even when i use much faster AS weapons, than it used to be.

So as thread suggests, i wonder if its intended feature of stealth nerfs, or a bug.
