Would it be possible to have another weekly mission, but a really hard and challenging one that last for hours?
Something in addition to the daily but adds e.g. 10 points to your daily reward system when done and as reward, if you reach the 36p. and then the 46+ points in total gives something more exclusive.
Maybe like a mission you can start on Monday and piece by piece complete in parallel with the daily ones and save the progress from day to day, if you not doing at least a 2-4 hour session. But which sends us out across large parts of the map in search of X, doing Y and fighting Z.
For example, just poking around but something finaly look like this with a little twist;
Collect 3 car batteries and 3 hand grenades on the South Coast in Minken bunker and construct 3 Ammo box to be left in a resistance stash on spot X in Marsland, after you destroyd any Fenix and/or Spetsnaz machines patrolling in the surrounding area.
BUT the twist - with less clues!
No X on the map as the current weekly mission, only starting with some instructions given and doing that you have to keep an eye for next reference to where about next order could be found, deciphered and explored. More like part of the original main/side quests that forced us to search and find our way forward in game and story.
If I could choose, I would rather have a more complicated and longer mission that gets harder the closer you get to completion. Maybe with rewards along the way instead of the daily repeats and roughly the same reward every level/week. Or why not 2, current beginner friendly and shorter (they are short!) and then the not so beginner friendly, longer quest that will challenge the players.
