Preliminary patch notes are up and still no DRK adjustments, I seriously doubt they're saving them as a big last minute reveal so I'd say it's safe to assume no DRK adjustments in 4.1.

Absolutely baffling, DRK offers nothing the other tanks don't have, it's now the only tank with no party wide mitigation and all of its cooldowns are weaker than the other tanks equivalents while also having less cooldowns than them.
