This might be sacrilege but I've never really used quick cast. I remember trying it ages ago and not liking it, and have never tried it since. I feel like I'd still prefer some with it off, but I'm gonna try playing with it on for a week or so. Took Rexxar into try mode with it on quick and it does feel better that way for Misha. Before "1" was the get stuff done Misha button, and D was the "abort! abort!" button mostly.
Try on release.
