eSports I feel needs to grow into a more spectator friendly approach. Real life soccer matches are not broadcast from a players perspective, for example. Similarly if CS GO matches are broadcast from a overhead view that covers a broad swath of the map, it could provide a more engaging view to the spectators.

It externalises the action, and makes the match into a "show" to watch, which I would say would be naturally more appealing to viewers.

Another interesting option would be to give spectators a free camera to view, I don't think that anything technical difficulty ia there in most game engines from providing a free, unrestricted camera to spectators.

You’re not bound by physical parameters... why not both?
