How bad are the issues with DRK?

[ManuelBravo]

Max level content is not the only content that is tanked. If a class does not feel functional compared to its peers at the same level blocks then there is a problem. Which is the case with DRK as it was re-balanced around an ability only available in 4 dungeons, 3 trials, and the current raid tier.

What about all of the rest of the content?

Even in lower content if you know your job it shouldn't be an issue. I main DRK for my Tank role option, I can tell you it's not the job, it's the player. If a person can't adapt, or is even willing to re learn a job than they should change it to a different role rather then complain. Over all all jobs were changed so even using the amount of content for a maxed level is more of an excuse. A tank can adjust to any situation if they are skilled or at a minimum practice with the actions they have.

Due to tbn it should fall behind warrior and ahead of pld in the dps department

Says who? Statistics? If a person knows the their job the only way it can be outclass if there is a better player with better gear / understands their role. While I may not be the best tank I consider my self well trained and can out class some tanks that are both better geared or considered better than DRK. Results is all that matters.
