Based upon CM god eye and F11 auto-tracking
Instead of relying upon joining a persons plane to watch a fight first hand, you can type in the following:
.watch <user 1> <user 2>
Doing so, it would give you a fixed-center tracking view in between both selected users....
When the two planes get close "let's say 3k" the tracker doesn't zoom in any further and will zoom out up until "let's say 8k" from each other giving you a constant panned center view that follows the fight from a respectable distance...
This arena option would only be enabled in the dueling arena and training arena...
Wouldn't you like to freely watch a good fight between two good pilots without relying on the film viewer or harassing people with plane join requests? Especially during KOTH, tournaments, and even training demonstrations...
