Reasonable on 16 September 2009
Well, I've joined Beta and I've never seen that so far. Enjoying the variety of modes, and loving the Cinema mode - oh, look at that kill! (Bows to Bungie as first people to have this I know of).
So maybe you're just unlucky? All may matches (whichever mode) have featured full weapon sets.
BTW, love the MP, really good - and the snow effects look cool.
Try to be reasonable... its easier than you think...
