As for me the Spectator could stand a few changes. 
First once it is very irritating to be packed immediately into a certain team. I’m aware that it’s not nice if on a full server people hang in Spec and block the slots. Nevertheless, one should be able to have a look first. :o
I do not know whether this is only with me in such a way, but if I change to Spectator, I can’t rejoin any team afterwards. Maybe this works via console, in Limbo it doesn’t. 
If one moves with the camera, “up” does not function, as for example “down”, “left” and “right” do. 
And in the end the most important. We need an In-Eyes-Spectator badly. One must be able to leftclick through players on a public server. Picking a player by clicking on his model should also work anytime. And If, in addition, this would also work by clicking the desired playername in the scores-tab, this would be simply fantastic. 
Cheers
