Spectator mode
Similar to what @Alphamalee said earlier about kill cams, maybe the possibility of a spectator mode wouldn’t be so bad considering how it would spark interest in newer or veteran players to watch other players play the game as it is. This could also be used as a learning opportunity for those that may be confused on some dungeons, as well as to maybe pass time as they watch a specific player they consider to be good do crazy ballsy and or cool stuff or possibly something of the dumbest quality.
How would it work?
The way this could work would be through a single player asking to spectate you and if you accept it, then it would allow multiple players to spectate you, there could also be an option in the settings where you dont need to hit accept for players to spectate you.
You would know when your being watched when a yellow highlighted text appears saying you are now being spectated! to obviosly show you that you are being watched at the moment.
Also a small icon maybe a beholder with a grey number would appear showing how many people are watching you, and as it increases it changes from grey -> Red -> Orange -> White
- Grey: 1-25
- Red: 26-50
- Orange: 51-99
- White 100+
(the icon would be on the bottom right corner of the players mini map)
