Hi! Emiin Vanih here, primary tank mentor and theorycrafter for The Balance, as well as The Theoryjerks. I was ignoring this post as best as I could until you flat out lied about TB's position on Dark Knight, and FFLogs.
For the most part you were being subjective, so I didn't really care about the topic. But when you misquoted both FFLogs and my personal stance, I had to step in.

FFLogs itself refutes the first claim of DRK being underpowered in DPS, in pretty much every percentile bracket. If you are considering logs for dungeons, there isn't any point in looking at them - no one actively competes in dungeons and many people play defensively.
At the moment,
Dark Knight is in the lead in all of our respective theory sheetwork. If you got any information from The Balance, you are clearly misrepresenting the work we have done since the patch has released.
Now that I've stated our record of fact, now I'll dissect your post.
Your ideas for every ability revolves around the idea of an AoE powerhouse. I'm not sure where you're getting the idea that we need any work in this matter. Having Syphon cleave, Abyssal doing 2.2x its damage, (more coming)
