Sure, I got a scrub team once (maybe I was lucky it wasn't more often than that) in CM. We ended up quitting. But in most cases, I end up getting a pretty decent team. Keep trying.
Also, it might be worthwhile doing lvl 1 with allies, maybe lvl 2 too, just to get you over the lump of players who just can't manage to get this completed. But I'm at level 5 now, most of which was gained via PUGs because unfortunately, Dii allies are great to team with but the few times we tried at the beginning of fractals, we've had problems with DC's and now I am not sure I want to attempt that again before the fix.
