+1 to everything what Anapingofness said.

I was debating on how much detail to add about gear and some other points. So, thank you Anapingofness. /bow <3

For myself and the gear used, I was very lucky to have the crafting resources of a large FC. You'll want to upgrade your gear and accessories every few levels, try to avoid more than a 4 or 5 level spread between your gear and job level.

(btw; I'm leveling WAR now, which is around level 35ish... I'm reliving the new tank experience except I know all of the dungeons this time, haha)
