If you look at the childish aggro battles we have now in the Crystal Tower series, its only going to get worse with the addition of Dark Knight. We all know its going to attract all the wrong people, and I feel sorry for any potential good DRKs that are going to be dragged down by its reputation.
However, my main concern is with Ninja's new skillset that manipulates enmity. Because the aggro wars aren't troublesome enough, now ninjas have an ability to increase the size of the tank's ego.
No thanks, I'll be running monk through Floating Continent, and laugh while the Derp Knights fight over aggro while adds are killing healers.
Edit:
I don't know where you guys get that I'm part of the aggro fight and/or have a hard on for being MT. I'll give an example:
The raid is now on King Behemoth, and tanks have been silent up to this point. So we're just standing there waiting for someone to pull, and I say "I'll get IG". So whatever, after a few more seconds of waiting a tank pulls KB, and the fight starts. When IG spawns, I voke it and pull it out of the middle. But NOPE, here comes superego voking it off of me and keeps it in the middle while KB readies meteor, and everyone dies. Fine, superego can tank it then. Next attempt, I'm minding my own business at the tower clicking off the charges, and once KB readies meteor for the second time, IG isnt dead, and superego runs behind a meteor with like 10 people and the comet is destroyed before meteor hits. A bunch of people die, and IG is running around cleaving everyone, as the other tanks gave no shits. So I pick it up and pull it away before the 3rd meteor, and intentionally died to meteor as IG wasn't dead and I was not going to wipe everyone unlike superego.
But here's the twist: I was blamed and votekicked. Now tell me this is not going to get worse in 3.0, and I'll tell you you're naive.
