God I hate quitters. It is especially worse when it is a group of 3, 2 being guests and so if one quits the whole box leaves and I am left by myself. Like this game:

Bah, I just opted to hide the whole game, of course they killed me here and there, because they were looking for me hard, but it was somewhat fun to have them run by me not knowing I was there.
As much as the radar is nice, it really has fucked Halo. No not the radar in general, but how accurate it is. I think it is worse than bloom. Having such an accurate radar lets people camp easier, know where to throw grenades, know exactly where you are coming at them. Of course you can work around the radar, but only so much.
In fact I thoroughly enjoy Pro game modes because there is no radar. At first I had trouble because I was too dependent on the radar, but I got used to it, and having that little bit of freedom of movement is nice.
