I was really excited for this to save my aching hands when sprinting for an extended duration (long time keyboard player). However, I'm finding it more troublesome than it's worth as I can't sprint and cast abilities. When sprint is toggled on, I have to full stop to cast an ability, remember to hit shift again for normal running when in content with combat. There's no message on the screen to let me know if i turned sprint off/on, I only know when i run and try to fire an ability, it doesn't work. It's quite frustrating to find your abilities not firing when maneuvering. Maybe some auto sprint toggle off when in combat or screen notification on/off might be helpful. The idea is great, but utilization is frustrating.
