I believe so, although I wouldn't swear to that. Either way you'd be missing out on 3 Golden ones and possibly some specials. It's not the end of the world but it would surprise me if you didn't. Don't use quick search, seriously. Server Browser + China Rising = Pretty fast. I'm guessing it will be even easier for Second Assault. I don't think quick search actually locates China Rising maps, when you search select the box for full games and then queue for one. It looks like nobody is playing but actually a lot of people are. Or try in the regions around you (Not ideal but you gotta do what you gotta do)
