I'm finding this very confusing and I can't seem to find consistent info. I'd like to get these all written down somewhere so I won't forget. So far I think I have:
Mordor Allegiance Weeklies:
Last day to complete is Sunday and Wednesday night (quests reset Monday and Thursday mornings EST.)
Northern Kingdoms: the same?
Reclaiming the Grey Weeklies: Last day to complete is Saturday night (quests reset on Sunday morning) Each wrapper can completed twice in one week.
The Vales weeklies: Someone in chat told me these reset every 7 days depending on when you started the weekly...so in other words there is no set day?
