There is no way in hell bard is top except on extremely movement heavy fights.

Dragoon is simming ~5% higher base potency wise, and that is without the bard's 10% hit on weapon damage.

I don't know monk enough to comment, and I don't have a good idea of DoM vs DoW atm, but at the very least perfect rotation DRG is better than perfect rotation bard.

Later in the week I will likely modify the sim so that it can handle random and fixed duration/time (normal distributed) downtimes to model melee more realistically.
