please add a self ping checker
I don't konw how many times other players or I have started a game only to find out in game that my internet is working sub-optimally. I would never have started to play a game if I knew my net was on the fritz. If you add a ping checker to the client then players would be able to tell if they were lagging in the first place.
TLDR - add a ping checker, will reduced number of crappy lag-blamed games for everyone
