BW isn't useless for the most part. Kind of pedantic to lock it out of Grit though. Just like it's pedantic to lock us out of MP battery skills like Mage's Ballad to have artificial skill ceilings for MP management and gimping a support class's support options. One of the few fights you probably won't have BW is final boss in Vault. Because that guy is mean.

If anything I want to see something happen with DRK in general. It is too reliant on it's healer to get anything done. Plus I hate Living Dead. And the fact all it's progressional skills just work against each other.
