Speed of the Hunt gem wastes charges

[[KotH]Mac]

I bought the Greater Speed of the Hunt gem and the first time I clicked on it, I took off running (being used to doing this on my Mins and my Skald). The sound started and then stopped, and I did not have speed. Trying again, it became clear that I have to stand still for the entire 5 second casting time. I am not complaining about that. The reason I am filing this bug report is that the first aborted attempt used up a charge !!! This should not be. A charge should not be used unless the speed spell was successfully cast.

This is a suggestion, not a bug.
