No. That's not accurate, either.
Forget about whether a player dashboards or that he/she is the host. When a match has started, a game, and a player decides not to continue that match or game, that is what the English language only a few years ago called a ... " forfeit ."
It's kind of like if two NFL teams were playing on the grid iron and one of the two teams decided they did not want to continue playing to the fourth quarter. They just walked out of the stadium. That's a forfeit. A forfeit means you surrender, you give up ...
... the team that forfeits accepts a loss.
It does not matter why they forfeit.
In Call of Duty, that same principle applies. If a player leaves a match before either team scores the maximum amount of points or before the time limit of the match has expired, then that player accepts a loss. It does not matter why the player leaves the match, the fact is, the player left and, therefore, is ASSUMED to have accepted a loss.
Before you get your panties in a wad reading this, continue reading and you'll get why a dashboarder does not get a loss.
What I described above assumes that every player that leaves a match does so with the in-game menu.
Of course, we all know that is not how everyone leaves a match.
Activision takes the position that there is no way to know why connection to the game is lost. Power outage, someone tripped over a wire, blah, blah, blah. That is a correct assertion. Therefore, the assumption by Activision has been, up to BO2, that the player that "lost connection" did not necessarily dashboard, but lost a connection and, MOST IMPORTANTLY, Activision assumes that the player would have stayed in the match were it not for a connection that was lost through no fault of their own.
The acknowledged and admitted by ATVI problem with all that is that, yes, some players can purposely cause the connection to be lost. That includes pressing the center Xbox button on a controller and then hitting Y in order to return to the XBL "dashboard" while in the midst of an ongoing match. The assumption has always been that this is a minority of players and, therefore, no reason to assume manipulation of the system in order to enhance performance results.
The key word is "assumption." ATVI admitted they have no concrete data to know whether or not "lost connections" are for legitimate reasons or if they are because players are manipulating the system.
Now, the REASON players that are not host are credited with a loss when a host dashboards is because your console is able to know whether or not you "lost connection" or you left the match. Since it was not you that dashboarded, then the game assumes you INTENTIONALLY left the game, retains that in the console's memory, and scores you a loss at the ATVI server that tracks such information.
If it sounds like a lot of unfair blabber, that's because it is a lot of blabber for something that should be much, much simpler to handle.
The probation for dashboarding, whether host or not, is a good intention, but not a valid solution. Here we have a company that laughs away threats of law suits from angry customers ... worried about whether or not they will be sued because players are credited losses because they lost connection?
The ONLY way you're ever going to substantially reduce "lost connections" is by first crediting players with a loss ... regardless of the reason they left a match. It is fully possible to credit lost connections with a loss. "Power outages," "accidentally pulled wires," "phone calls," etc, etc, etc, BE DAMNED.
If you leave a match, you get a loss. Period. End of conversation.
And if you leave because of lost connection, then progressively longer probation periods should be enforced.
If a player uses the in-game menu to leave a match, that player scores a loss and should not get any further actions taken against them.
That is the solution. It is easy, it makes sense, is fair, and, most important of all?
It does not ruin the gaming experience for other players.
