If you have a perfectly functional system, why would you replace it?
To "modernize" the game?
The problem with these constant "modernizations" you see with updates and live service is that if you implement them poorly - you take the game back 10 years instead of forward. Going from Quickplay (pbuh) to matchmaking is like going from the Ford Model T to the horse and buggy, except the horse is blind and the buggy is Gabe Newell's belly.
