Or they could simply be more interested in the Season 2 storyline and gameplay as opposed to content from 8 years ago. How people engage with the game is not for you to decide, whether or not someone spends 2 months doing the story vs rushing it to go hang out in Island Sanctuary or go raiding isn't anyone's business but their own.
Of course this partly depends on how much Season 2 will draw upon the base setup by Season 1. We still have literally no idea what they have planned for the story but it'll almost certainly involve the continued adventures of a hamburger-eating cat and two elf twins who can't help but cause regime change wherever they go, it seems.
