Please Give me Observer mode

I really want to commentate/Observe other pros going at it and make really good videos before they quit. As much as i love playing high level matches. Getting to watch 2 players go at it from an observer point of view and being able to make videos/commentate is just something else entirely. If I could have 1 wish it would be to add this in… If it cant be added in due to issues. At least take fog of war away so when i quit I can see the whole map… Please…
