It would be nice if I could see how robust the other players' latency / ping speeds are by a simple color indicator by their gamer name. Red is "bad"; Yellow is "warning"; Green is "good".
Destiny does this to great effect. I can quickly look at the colors during the match and see if there are lots of "red" players. If there are, then I leave the match and find a highly "green" populated one.
It doesn't have to be numbers (I don't need that granularity of detail). Simple colors will suffice.
NOTE: This is for consoles.
