At the moment, it takes way too long to fill up the slots for people that left a game. If the game is a blowout or it's close, that's understandable and honestly preferable. However if you have a game that's tied, and even moreso if your team is doing well, and a few people on your team leave, it shouldn't take 5 minutes to fill up the slots on your team with new players.

An example: I was in a game of control where it was a 4v4 and tied one one, and I was on about a 15 gunstreak, but two of our teammates left. So it took one and a half rounds for new ones to come in, and at that point the game was pretty much over. And to rub salt in the wound they ended up putting one more on their team so it ended up being a 4v5. Ridiculous.
