I've had just about enough of Crysis 2's multiplayer, I had some faith going in after patch 1.4 only to be let down big time. They said they fixed the problem of losing progress, losing your levels, upgrades and all.
I went in, had a match, unlocked an attachment/module for my grendel, I chose to unlock a reflex sight. Played another match, came back see my reflex sight locked and no module unlock to bring it back. I also unlocked a reward dogtag (those ones where you can choose a dogtag to unlock) at the main menu (not in a server), had a match, came back to see it was locked.
All I can say is

I've lost so much level progress, so many modules, so many dogtags! And I'm just over it, it's really all been a waste of time. I mean I can say I’ve enjoyed playing Crysis 2's multiplayer, it can be fun. But for a game that's been so heavily advertised on multiplayer and a "very rewarding" levelling system, it just makes it fall short.
I believe Crysis 2's multiplayer can be so much better than this. I want to enjoy this game.
I've given up on C2's multiplayer for now, when multiplayer is fully functioning and plays how it's supposed to (I wonder how many patches it'll take to get there), I might consider playing it some more.
So, what's you multiplayer experience in Crysis 2 been like? As bad as mine, you given up too for now?
I highly doubt you will see a patch beyond 1.5 or 1.6 . After that, they'll just dump it.
