If a player on your team leaves the match early you should not be penalized. I have been playing for a couple hours so far tonight and I have been in many matches where my teammates would leave early. This obviously results in a very hard match up where you will most likely lose. Therefore detracting from your skill rank. I went from a Gold 6, about a win or two away from Platinum, to a Gold 4… In under two hours…
There should be a system in place that prevents this. We should not be demoted for something that is out of our control. It should go the other way too, if you beat a team with 3 or less players then you should not be rewarded as much for beating them. The fact that the game has been out for this long and this is still an issue is deeply troubling. If anybody else find this annoying then let 343 know.
