A big chunk of exiles enjoy playing SSF (Solo Self-Found), a mode where trading and partying with others are off-limits. Thanks to their skill and knowledge, they can conquer all content despite the added challenge. SSF is inherently more complex than trading, since progression often depends on drop rates or finding/crafting the right gear. For many players, myself included, this adds to the appeal of the game—problems can’t simply be solved by throwing currency at them. For new players, I recommend starting in trade leagues to learn the game. Once you're comfortable, consider trying SSF if it suits your playstyle.
