I have never actually played PS4, but from playing Xbox, yes...typing without a keyboard is a pain.

I would use a keyboard that attaches to your controller. However, I don’t know how good these work.

You can be every class on one character. All fighting, gathering, crafting classes.

In addition to a comment I saw about throwing away old gear: I would avoid doing this if you ever want to get into crafting because you can desythedis these for meterials. You can also sell them to your Grand Company quartermaster I think. Also, I use old gear all the time when leveling up new classes.

For a Bard, you need to complete all of your class quests up to level 30. I think these are normally found at the Archer’s guild in Gridania. Then you will get a quest to become a Bard.
