We all know how annoying it is, get into a good team of three or four sometimes even two and the leader has to go, and the team gets destroyed. It would be a great upgrade if the leader could give others the ownership of the team or even when the owner/ leader leaves, the team owner goes to the oldest (Longest) member in the team.
It would be a great feature (but kind of pointless at the same time), handing out team leader to a random player of the team, possibly even the 2nd teammate who joined.
Its not completely pointless, while it's annoying when your team mate has to leave so I think it will be a minor change but useful in some situations.
