Currently the Tales of Adventure boosting options allow you to instantly boost a single job to level 70, which definitely has it's pros and cons, it's great if you want to get straight into high level content, especially if you're already max level on your first job and want to try a second, but it can also be very overwhelming as it throws you in at the deep end with every skill up to 70 unlocked at once and dumped relatively unorganised onto your hotbar depriving you of the opportunity to learn how to play the job and use all of its abilities naturally as you would have it you levelled normally.

At the same time if you're used to playing a job at a higher level, starting to level a new class from scratch without boosting can feel extremely tedious for a decent chunk of time until you've unlocked enough abilities to at least make your rotation feel reasonably engaging.

What I would therefore like to suggest is a broader middle-ground, a new "Tales of Adventure: One Neophiles Journey", which instead of boosting ONE job all the way to level 70, boosts EVERY not already unlocked/leveled-up ARR base class to level 30 and completes all but the level 30 Job quest for each of them, then allows you do each job quest to unlock them and organically learn the Job from that point onwards.

TL;DR: I would really like to try every JOB eventually, but I really don't want to have to level 1-30 on every base class first to do it or pay to boost every job to 70 and then have to read/watch guides to figure out wtf i'm doing! :/
