It is a big plus point in FF14 that there is no rule how to play the game. There is no raid or die, there is no login every day or if not you will stay behind. You like another job (Class), just do it. Your only into crafting, go ahead, no need for running dungeons.
I am not so long playing FF14, but so far what i have seen we have plenty of different play styles in the game and that s perfect as it is.
