Many teams would like to do group training and command review of tactics from a high level 3rd person view, similar to the last tournament view that was used by Devs watching the matches.
I and my team and probably many other could use this option for team improvement and training.
Effectively this help make Private Matches more useful for team training, since we don't have a team training grounds. Unless you make a team training grounds, then this option should be there too.
