In case no one has told you, Bungie, seeing as how you've made it abundantly clear since the beta of Destiny 1 that the community knows how to do your job better than you:
So far as the gaming world goes, "scheduled maintenance" is not "regular" or "scheduled" just because you put out a notice a couple of hours ahead of time.
Pick a day. Pick a time window. And lordy lordy, boom. Scheduled maintenance your community knows about well beforehand.
And before anyone brings it up, no. Social media posts of any kind do NOT count as forewarning. I should not have to pay attention to an entirely third party site to get info from the devs. Period. Plain and simple.
