This doesn't even make sense. What situational awareness does a bard need that monk doesn't? You need to know where the boss is facing so bard can hit its positionals (oh wait...)? Dodge AoE (because monk auto-dodges AoE, oh wait...)? Move while attacking (not even going to bite this one, you can move 40% of the time because cast is 1.5 seconds and you can use feint if you need to move for more than that). By every definition of the term, bard has less situational awareness tank monk and easily fits the description of easiest class. Also fit the OP question of easier class to play since he considers BLM to be easy.
