Blood Weapon / other DRK suggestions:

and that's with my DRK being my alt Job at ~i216 selling content with i230+ dps

Whelp try tanking experts in i203... :X

Burning expensive cooldowns on cooldown at the cost of more offensive might when the mitigation is NOT REQUIRED (i.e. small trash pulls) is playing poorly, even if you are a tank.

One DA'd hit more or less won't make the mob die notably faster. Tank DPS is not high enough for that.
