The main adjustment that has to be made is to promote reclearing content with those who havent cleared it yet, regardless of whether its savage/extreme or normal.
In the current state once you completed the duty, you are promoted to never join one that hasnt completed it yet. Its just less hassle and because they are more likely to have better gear, has a significant advantage even if players were equaly skilled.
Weekly tresholds in the current way are terrible on that. Its counter productive to reclear it. Made even worse when people are progging in m3s and you are still stuck in m2s.
And once the week treshold is reached, you are now permanently behind, there is no way to ever catch up, just because of being unlucky in PF. (and yes, its luck, since anyone decent to clear it, is instantly gone from the pool of potential players that join, once they cleared it). You can be harsh at joining diffirent PFs at the slighest indication of them not being able to clear. But it still has its limits on how effective it is.
Statics are extremely advantageous here, yet the game is completely missing features to promote/aid people to find one. Linkshells/FCs are not effective at all (especialy with how limited we are in numbers here).
The best bet is to just have a friend that can invite you to a party in PF that has its join requirement set to cleared, just to get people of which you know are capable of clearing it. And even then, its limited in effect because of the warning it gives.
