Random thought for DRK ability in expansion

[Reynhart]

Experienced DRK already has Blood Weapon access even when tanking.

You can indeed tank without Grit to have access to Blood Weapon. But Main Tanking while spending HP to power up your attack...I'm not sure it would go very well. And since SoulEater only leech while in Grit, having DarkSide cost HP out of Grit would create a clear difference between the OT and the MT role.

Could be interesting, with the proper balance.

The problem is not that DRK/WAR is the best comp, which really depends on the content you do. It's that PLD/WAR and DRK/WAR are better than PLD/DRK and DRK/PLD because PLD and DRK don't offer much in the OT role while losing access to some MT skills.
