From what I understand your stat priorities are essentially Crit -> DH -> Det. I don't know how bad skill speed is persay but from my understanding you don't really benefit from it as BRD.

Essentially my logic with BRD melds tends to be.

1. Does the gear need more crit on it? Meld Crit
2. Does the gear need more DH on it? Meld DH
3. Does the gear have enough Crit and DH on it? Meld Det.

However. I would personally check on the Balance discord before you take what I've said as Gospel truth.
