Since my return, I've been logging more hours in the TA than anywhere else.  I've run into a few new guys here and there, but I'm usually by myself (or with a friend that recently joined).  I think one of the biggest issues I've run into is what the OP referenced = communication.  I hardly ever get a response even after explaining how to operate the radio/chat bar.  I think an arena message prompting how to use the radio might be effective?  I also think requiring new players to log "x" amount of minutes in the Training Arena before entering the MA would also be effective.  The only problem with that is what I mentioned earlier and how empty the TA usually is.  Literally, I've been the only one there almost every time I've logged in.
