Bard is definitely the easiest.
No combo,can move while dpsing,fast out-GCD(is that the correct term?) skills with low CD.
And i'm not the only one thinking this.But even if it's the "easiest" job there are a lot of players who still can't dps properly sometimes.
It's like any class/job they're all "easy" in my opinion but there are details or sometimes more importants actions to do/not do that show to everyone if you can play this class.When i see a BLM going fire/fire/fire to reach astral fire 3.... i can't hardly believe this by example.
