Separate dodge roll and sprint

I'm playing a blink build currently. I never dodge roll or sprint. There are many times when I blink my character comes out of the blink and stops moving like I've just canceled out of a sprint.

Maybe I'm being too heavy handed with my space bar, maybe I need a new keyboard, or maybe you should bind sprint to shift like any other game in existance with a sprint mechanic.

Even if you ignore my plight, just look at how it is and ask yourself - "on what planet would anyone dodge roll to enter into a sprint?"

Update: I realise it got alot worse after adding an extra 40% cast speed on rings. So I'm going to have to very quickly love tap my space bar from now on if I wish to adapt.
