I don't think the problem lies in Foe Requiem vs Hypercharge though.
The problem of Bard vs MCH at the moment is the huge gap in DPS between the two classes, their attributions as well as their end game raid content kit.

Square Enix need to decide something at this point, is MCH a support DPS or just a ranged DPS, I don't think the game really need a Bard clone, they really need to change the class so they don't look so similar, just look at healers kit, WHM is a huge heal machine, SCH is a nice off-healer DPS and AS provide some nice DPS support, none of them have the same kit.

I could live with the damage gap if Square Enix decide that MCH is a flat out DPS class, just like a Monk but ranged, but right now it's a Bard clone with more DPS and better end game raid content kit.
As for their kit, it would be kinda cool if Square Enix would not release such blatent lack of proper kit for a class when they release new Raids. Either addapt the raid or addapt the classes.
