Plunge is like at least 2-3% of your dps alone, without even considering the additional MP it grants during Blood Weapon. I mean, why would you willingly and knowingly do less damage? It's literally 1 more button to push every 30 seconds. You wouldn't think it's acceptable for a DRG to not use Jump, would you? Or a SCH to forgo Energy Drain?
To put it into perspective, Plunge is 400 potency a minute. Carve and Spit is 450 potency a minute. You wouldn't ignore Carve and Spit, would you?
Assuming you mean 100pot/15s cd (same as Onslaught), you just essentially give drk extra 53-105potency/minute, if they run 11 or 12hit Delirium gcd, respectively.
But if you mean make Plunge cost 20blood gauge then congratulations you make DRK unplayable. Onslaught and Upheaval cost 20 because Path gives 20. Souleater gives 10.
And if you think buffing Souleater to give 20 is fine, it isnt. DRK already plays like a bad WAR, that would just cement it.
The only change Plunge needs is a much faster animation, like Shoulder Tackle or Onslaught.
