that was a problem of their own design, don't blame that on the players. between 2.1 and 2.2 Coil was gated so it can only be done once, CT was gated so you can only get 1 item. they added roulette which was great for capping myths but it also meant combined with CT players ran a lot fewer dungeons then when they were doing AK and WP speed runs. the EX primals only needed to be done once a week, and for those that weren't able to one-shot them, all the failed attempts accrued no FC points.
it's their fault that everything players wanted to do prior to this patch can only be done once or gave no points for attempting them.
