Ok so the MCC works pretty well for me matchmaking wise nowadays, it matches me fast, most of the time on even teams and without lag.
BUT here are the biggest problems for moe of the game, that weren't addressed so far:
-Gametypes, we had this already, there are so dumb combinations in so many playlists. (Why the hell is Stonetown in ranked)
-the ranking system, is it even on? I get matched across the board of numbers, If I win 2 games in a row and don't rank up from 9 to 10 but lose one and go down to 7, I'm not so sure it works like intended, 2 days ago I ranked down after winning a match.
- Quitters, I know it is a tough problem and it is the community who is at fault, but damn quitters, afk' dudes and betryals are in Halo like in no other game, why can't we do something against this.
Oh yeah and the game is still going strong with resetting my campaign checkpoints.
