I'd like to see the 'Complete 3 or 6 Daily Quests' quest be persistent between days. During the week I have fairly limited time to complete 3 daily as is and now don't feel like it's worth the effort to grab these quests if I can't finish them.
I'd suggest all Daily Quests should be persistent between days, but each quest is limited to turning in 1 per day per quest, meaning if you hand in the mission terminal quest today, you can pick it back up but must wait til the following day to turn in.
This QoL would also help players who prefer to do specific dailies with their time, without forcing them to get into content they normally wouldn't. I get there are a lot of choices, but many of those choices require a time investment and/or grouping up.
