Rather than having weekly quests set 7 days after completion, please change it so that weekly quests reset on a weekly reset day, like every patch day, or what is usually patch day.  Before seasons I didn't really care about weekly quests because they didn't take extremely long to do most of the time.  However now with the 5k kill quests, they can take 2-3 hours, which can burn someone out rather quickly leading you to want to do the quests over multiple days, but since the timer doesn't start until after you turn a quest in you feel like you have wasted days if you don't just blast that quest.  Same thing goes for the Intact Nouver scale boss quest.

TLDR Have a weekly reset time much like you have a daily reset time.
