Hand of Chayula skill stops hitting at high attack speeds

Hand of Chayula skill seems to have some poor interactions with attack speed. At high speeds the skill takes multiple casts to actually hit enemies. The teleport works, however it takes another 2-3 casts after the initial teleport to hit enemies with the skill. There appears to be a threshold around .3 attack speed where this interaction gets really bad and it feels like a useless skill at that speed.

I just encountered this issue. I have Hand of Wisdom and Action which gives attack speed based on dex. I'm at a point where if I get a +8 dex passive node the increased attack speed causes Hand of Chayula to be very inconsistent. Refunding that passive point makes it reliable again.
