Summon reaper of eviscerating

I recently found a bug with the Summon reaper of eviscerating! While building my summon reaper build I wanted to stack cast speed to make my reaper attack faster of course but there is an issue! once I reach .42 cast speed the animation for the reaper full bugs! the animation doesn't perform full and all damage is negated! I have a video I will be posting with this for a better explanation!

Has been this issue addressed? With anought cast speed you just animation lock your minion whom does not preform any attacks...

Stacking cast speed should be a valid play style to this minion..

Confirming that this bug still exists. The Reapers action speed doesn't scale with your action speed so you end up cancelling its attack over and over again when you have too much action/cast speed.

Same for me. This skill is unique in that the attack speed of the reaper is limited by player`s cast speed. I had the idea to speed up the reaper with Mokou embrace rings and self ignite, as well as or with the Inquisitor's Fanaticism buff. Both options eventually led me to this bug. At this time not fixed.
