Should sprint be tied to roll?..

The only benefit I see is less overall buttons to push ("thanks" to gamepad users).
BUT using one button for two separate actions feels pretty damn clunky. Doing roll when you need to run is just annoying. But sprinting when you only wanna do roll is potentially deadly, especially if you run into that heavy stun.
So should it be on the same button?
Or should there be at least an option to put it on two separate buttons if you prefer it?

i dont have any problems with sprinting tied on 1 buttons, never messed the thing but seeing how many are having problems one thing to do could be to increase the hold time to start sprinting, since you're not sprinting on mob packs but once they're all dead, this way dodge triggering sprint shouldnt be a problem anymore unless you sleep on dodge button, then it's your fault.
