Same. I jumped into CTF and was in a 5v2 within a minute. Then, the other team was spawn-camping us on Ragnarok with a Mantis, a Warthog (with a gunner and sniper riding shotgun), and another sniper way up high on a cliff area on which you're probably not even supposed to be able to stand. I would never spawn inside the base, always out in the open, and they knew the spawn points, suggesting they had probably done this before. Pretty soon, it was a 5v1. Of course, they completely ignored the objective (Neutral Flag) and let the time run out, farming kills. The dudes had things in their bios like "#34 in Wheelman medals in Halo 4".
