Might Start Over

Reading between the lines so this could be wrong - but are you making a different character for each class? In ffxiv one character can learn all the classes.

They've got themselves registered as a level 11 archer so you're probably right.

OP: At level 15 main story quest, you get the world unlocked for you and I believe the level 15 job quest will also notify you that you can equip other weapons and become a new class at any instance of your own free will. Bear this in mind as well as utilizing that exp boost.

It's after the level 10 class quest of your starting class that you unlock the ability to add others. But reaching the Envoy quest at level 15 in the MSQ gives you access to all three of the starting cities, so there are more classes whose starting/unlocking point you can reach after that.
