Skeletal Reaver Minion: rage doesn't increase attack speed

Command description says: "Skeletal Reavers do more Attack Damage and gain increased Attack speed based on their Rage". Just tested it: it has no effect nor visually, nor in the tooltip.

This is a huge problem that makes their use unprofitable.

Without Rage


With some Rage (likely not 30 Rage since it was just 1 minion on a few mobs)


You can see it having Rage gained on hit and the damage going up, but the Attack Time and Attacks per second do not change.
