Dark Knight Simple yet effective buff idea

[Terhix]

The design of dark knight in FFXIV since the patch it was introduced is that it can choose to spend MP on damage or defenses. You might as well remove the job from the game if you remove the MP from the darkness spells. If you want that job, play warrior.

There is no choice in DRK toolkit between spending MP on defense or dps, there hasn't been for years. If you ever spend MP on TBN and it doesn't break, that's not "oh I made this choice and I got this tradeoff", it's a mistake, every time all the time.
