I could believe that. The people who work on a game, know its featureset and the way its intended to be played. Real competitors don't give a shit, they'll resort to fun-killing tactics to get a kill/win.
I played a little MP last night, I'm still not used to all the maps, but they seem designed to have open areas with plenty of cover, and indoor / wreckage areas you can use for positional advantage or laying traps. They *are* a little on the large side for 6v6, so if they add new maps later on, hopefully they include a couple of small ones. If it weren't for the occasionally assholish spawning, this would feel a lot less chaotic than BO2, and I think that might be a good thing. I think people might camp more because of what you've suggested, but that could equally be because they're not intimately knowledgeable of the larger/complex levels yet. I find the automatic audio-callouts from players' characters make it interesting and potentially helpful... you're being told when someone is on the balcony, first level, or out in the open, as soon as someone makes line-of-sight... I don't think you can necessarily play the same way you played in BO2, but that's not to say you can't play and become skilled at MP in this game.
I was reading on the COD forums that dedicated servers aren't up for all platforms in all regions yet, so if you're having technical MP issues or migrating hosts - that's why. There are suggestions that a few things are fixed in the next patch as well.
