Questing will make your base levels go pretty fast but you have to grind the class levels. Repeatable quests (blue "!") are available in every region after you complete a certain chain of quests in that map too. I'd say normal quests will get you maybe 30-50% of your level on average?
As for time, it takes about 2-3 hours a level at 40 doing repeatable quests if I use my martial artist. Working back I guess you could do 1-40 in ~30 hours?
Once you hit 40 base though you're looking at another 5 hours+ each class for 1-40 lolol.
I haven't really done the party quests either, gonna see if I can do the 14 one now lol.
