In combat you dont want to be sprinting unless your doing a sprinting attack. So technically not 100%.

This is something we have considered before, so we'll see if it's a feature we can add. But as was written here before, part of why it is the way it is is because of combat. You aren't always going to want to be sprinting, else you will constantly run into enemies or do dash attacks when you want to do a regular melee attack.

Tough to say, but I'll pass your feedback along!

EDIT: Also, you can technically keep sprinting by briefly holding the sprint button and letting go of the sprint button, but as soon as you stop moving it resets to the default walk speed.
