Should Dark Knight get a Rework?

[Rehayem]

I mean, its already a shield tank with it having so much heavy focus on TBN. So why not go all in? xD

Would be cool, but that would render Sage useless, no? DRK's combat style focuses on sacrificing HP for damage (in our case in FFXIV it's MP), so they could work around that, maybe it would be a spicier gameplay.
