When you host a server and are setting up a game (but have not started it, yet), it would be good to know whether there are users connected who will lag a lot during the game. As such, it would be good to display, for each connected user, the average latency of this connection. Color coding could be used to indicate problematic latencies (e.g. mark latencies of >200 ms in yellow and >300ms in red color). This way the server admin would be able to make informed decisions.
In a next step, users should also be able to see these values, both for themselves and for other users (proxied through the server), so they can tell on their own whether or not it makes sense for them to play on this server. Ideally average latencies, caclulated by the client by pinging all available servers, should also be displayed on the lobby screen already.
If possible, not just average latencies but also jitter should be displayed and color coded. Alternatively, if there is only room for one indicator, it should be possible to display a network reliability indicator which combines both factors with a logical OR, e.g. if the average latency is fine but jitter is problematic, display a problem status for the network reliability indicator.
