I haven't encountered too many problems with spawn killing, it happens occasionally, and yes it's damn annoying, but then it happens now and then in most shooters.
Glitchy, yes. I think this ties in with lag problems though. I've seen things happen on-screen that are completely unexplainable. Then when you play the video back in theater mode, it shows the incident without lag, which looks different to how you saw it unfold. So in reality while you think you're 10 steps away from a guy, it shows you as being only 5 steps away in the replay.
Although sometimes even watching the replay, it's hard to makes sense of how exactly something happened the way it did.
I don't play ranked games, so I don't encounter any restarter acccounts. I do enjoy playing skilled opponents though, it's no fun dominating new players.
That's the first I've heard of rapid fire controllers. I must look out for that.
Overall, I wish Halo 3 ran on dedicated servers. Perhaps even splitting Europe and America. Lag problems can make some games totally unplayable, and give players with better connections/host the advantage. Blue-screen, host switiching and long waiting times for games are also other problems I'd rather not have.
