Have developers of multiplayer lost their marbles and think matchmaking is great?

I'm not sure why you put this here. The answers section is to ask for help regarding an issue you're having but you're making a request to the game developers to change a major part of their game to something that as far as i can recall was never part the Gears series though I do admit that i did not play much MP of Gears 1&2.

If you want to complain about an aspect of the game head over to the boards and vent your anger there or better yet go to epic forums and make a suggestion there and who knows, they might listen to you but the chances of them changing the entire matchmaking system are slim to none unless it's broken to the point where no one can play at all.
