[client] - needs to be a quick and easy way to exit/re-enter when game is crashing

When the game is frozen (attempting to reconnect), etc there should be a quick and easy way to reset the system, maybe even in game without reloading. However sometimes it freezes completely I have to resort to ctrl+alt+delete but this takes while to determine the game is not responding because the client itself was designed to stay open so that people could not exit games by mistake. There has got to a be a better way to do this - I do not like to compare but I have never had WoW or similar crash as much even during huge raids. And its not just me but it always seems to happen every few games to myself, a friend, or another player and I am not sure if these are server, client, or user issues.
