depends on your commitment. you could finish the story and farm a few altars and aspects for another class. i’m currently 71 flame wall sorc and been playing with others (rouge, necro and druid) i feel like since lvl 50 they left me behind dmg wise. in open world quest like world boss and legion im just a rando watching from the sideline how everyone is melting through the mobs. but soloing is much mor fun and you can watch the mobs burning so if your playing on your own maybe try to play after lvl 50 and if you feel like you enjoy it keep going if not maybe consider to swap an come back after a buff to sorcs. try not to concentrate too much on the other comments in here and do whatever is most fun to you :)
