The join games in progress feature is terrible. While it was good in theory, an overwhelming amount of games that we are paired to this way are losing matches. Now, I'm a decent player but I can't pull my team out of the 100 ft hole that they are usually in when I join. I hope this feature is removed because over all it is an inconvience and an annoyance. I would almost rather play Reach than deal with this on a regular basis. I know there are plenty of people who feel the same way I do, and I hope 343 rectifies this soon.
