Pls let us can change server and check ping.

You can do this, at least I can on my xbox. Before signing in you can see which server you're connected to and see the ping. I dunno which button I pressed anymore to see it, but you'll see different servers and can connect to a different one. Just press all the buttons, one will surely be the one. I must say tho, this server feature only stood out to me after having problems with logging in. So, I hope it's not dependable on that for you just to be abe to change the servers.

Good luck
