Bard is the most difficult ranged job in the game (its not really hard its just, its competition is easier by alot that im sure children can main it) Knowing what each song does for you and knowing when to utilize them is key aswell as utlitizng ur support skills like battle voice, minne and paean. Far more crucial than numbers so long as ur Ilvl is up to date you should be solid never worry about worst and best those have the potential to change anytime anywhere play what you like.
