1.21 Pre-1 increased attack speed of the mace so players could chain charged attacks with wind burst, however it's not quite enough for consistency do this.
Players get to do critical attacks very inconsistently, which is the issue.
In the attached video, you can see in the subtitles that "critical" and "weak" attacks happen randomly and interchangeably, making the mace damage unreliable and random.
The possible fixes are to either revert the mace attack speed so players consistently do weak attacks with wind burst, or (preferably) slightly increase the mace attack speed so players consistently do critical attacks.
