Dark Knight Idea thread: Suggestions

[Nektulos-Tuor]

These are suggestions I would make to change the Dark Knight class, these are not something I would ask to change all at once, but these are to make the class more fun altogether and more practical compared to other tanks. Right now I believe they are unpowered compared to both Paladin and Warrior for plainly obvious reasons.

I stayed with the life-tap theme, however I also added some penalties to the abilities. Giving them a more unique flavor altogether.

Darkside:
Remove the Aura effect altogether and replace it to something like this:
