Question 1! as someone that loves melee classes tanks or dd which class would be best to rank up first, or which classes are more subjob related like war and nin where in ffxi?

First you should get the ability "Second Wind" from pugilist which is at level 6. Its beneficial to every single class you'll be leveling up. There are also a few other abilities but, IMO, that one is the most important.

For end game DD classes, you'll want archer at 42 for some of their (- enmity) abilities.

If you want a class that can probably get to 50 the quickest, I'd say White Mage.

Personally, I'm trying to get all jobs to 30 (At least 15) and then eventually 50.
