I can't imagine BLM's being too happy when their rotation goes down the toilet and they loose enochian because the tank decided to drain their mana.

I'm more than happy to have more dark themes on jobs but two major parts of your job idea will never happen, multi-role and stance dancing. We've already had these things, and the developers have already decided they don't like it and removed stance dancing. If there is anything that gives YoshiP nightmares it's 1.0, if there are 2 things that give him nightmares it's 1.0 and Arcanist.
