I know that players can spectate other players matches if they are friends with them. What I want to know is, how I can spectate a game while in that game itself.
For instance, sometimes I see someone with a very cool hero skin that I want to see what it looks like in combat, so I'd like to spectate them. Or I'd like to spectate a player who looks like they know what they're doing and has good skills so I can learn from them.
How can I spectate a match in a game I am currently in?
