I think share Control is nice, because if you play in a Team, you can buy or use other players Zeppelin. And if 1 player of the Team must go like 30 min. afk. but we need them , so all have to wait for him.
With share control, we can control his hero and are again complete TEAM!
SO please do not deactivated it.
Its really usefull !
have a nice day
greetings
