Dark Knight

[Lemuria]

so is the general idea that a lot of people who wanted to play DRK are now not going to play DRK because they don't want to tank?

I think it's more that they would have preferred Dark Knight to stick to its roots rather then deviating quite so horrendously. Going from an outright DPS to a tank is a pretty big leap, especially for a job which traditionally sacrifices HP to fight.

It means either (a) Dark Knight is going to be missing most of its iconic nature or (b) it's going to be the most annoying tank for healers ever devised.
