I guess we shouldn't be complaining that they're actually doing the proper maintenance ahead of time before things become a problem. Remember a few years ago, I think it was during the winter holidays, that something was going funky and people were dying for no reason from just walking across flat surfaces or from a small jump? I'm pretty sure I recall them stating it was due to some kind of "gremlin" in the system which was fixed with a quick hour long "server maintenance" session.
The later rest sucks as well... I am wondering if they have changed the way things work. Iron Banner used to be turned on by a switch (Bungie's term), but now it seems like they have to take the servers down and do things to turn on IB or the Faction Rallies.
