Waypoint Moderators aren't really Moderators, just power hungry and its goal is defend their beloved Halo at all costs. (Meaning that they wank Halo too much.)
BS Angel is alleged foe so, be wary of Waypoint and its moderators! Do not attempt to move to Waypoint. Enter your own risk.
*WARNING* IT IS MY OPINION.
IMO, it'd be 7-8 depending on the story. Remember Frankie saying that they'd be willing to change some canon to make this story...
That bit worries me greatly. Now UNSC appearing at Halo 4 and possible return of Covenant is sounding to be blatantly stupid to be honest. If anyone have followed the books, you would know that it is not good.
However, I hope that 343i would do good job with this. As long they don't use Reach core mechanics...
