I have multiple characters (2 of which have gone through to Leviathan story, one is around or behind titan normal, rest barely been touched).

Of the two characters I did level, one is my main and one is my alt.

Both characters have multiple jobs at 50.

My main's main is WHM (92), my alt's main is PLD (84). I have PLD and WHM leveled on either character, my main having 84 PLD as well. So both are my main jobs I guess.
