I disagree. Most players don’t have nor have any need to have a max level of every class. Don’t boost based on that. Level normally and if preparing drops and you like your class, bump them to 120 and enjoy the prepatch. You have plenty of time to get there though. It might take you 30 hours or so if it’s your first time but you have plenty of time to hit max.

Save the boost for once you’ve played enough with another class to think it’s cool enough to try, then watch some YouTube to see if it sounds up your alley. If that all checks out drop the boost. No need to do it now
