Retire heroes

As we all know some people from the community demanded the possibility to retire heroes since sometimes some heroes are of no use anymore, I’d also suggest that since losing many heroes can also lower your legacy rank points, which would be bad for some players. My suggest Would be to put a retire button for heroes that when clicked and confirmed the hero will stay 6-12 hours without the ability to move or take any other action, that many hours is to prevent people from deleting a hero and repositioning others in important places
