I want this to work exactly like viewing a weapon's status.
You move your cursor onto the 'connection indicator' top right of your screen and it shows your ping.
So that Asians/Aussies like me who don't deserve a server will know NOT TO TOUCH THIS GAME WHEN WE HAVE 300+ PING.
It gets annoying when going into missions finding everything teleporting around.
Though zaffy is probably right, I doubt there's a real reason to include a ping indicator when you can do it yourself fairly simply.
I always found any kind of internet related graph silly.
In order to see them ingame you have to start the game right?
But once you are in the game, you'll naturally notice any lag, you dont need a graph for that.
So you gain nothing. Only a random number to yell at.
I never pay attention to Ping indicators XD Even if they are right in front of my face :P
I think you need to learn the concept of latency lag.
You can test your ping here at http://www.speedtest.net/ and test it on the Virginia USA server, and Ireland server.
If you have a 1 bar, then there is no point looking over whether you have that extra 100ms ping difference. Teleporting, or rubberbanding, is just basically an unstable connection.
