I've watched Xenos video of Dark Knight, and he is pretty much right. The job needs a re-work and sucks to play, and no not "buffs" learn the meaning. I've never denied the job needs re-work, I've been denying grant the job more buffs when it is best on DPS currently. Dark Knight needs support what others obtained, than a copy paste of animations. At the same time as I keep saying, you have to be careful what changes you make, you can easily make the job too powerful adding extra buffs, or extra potency, many game genres examples have proven this enough.

Needs re-work, not more buffs to make it ultimately a lot more powerful in all content, it sucks in Dungeons, it's fine in content that isn't dungeons. It isn't fun to play, it's a 50 Cal LMG, then it becomes reload time which is a chore.

TBN: Obtained Cure Potency 400-500 if the barrier is broken (Buff)
TBN: Cost no MP, cooldown increased to 25-30s, buff timer extended 12s. (Re-work)

Reactive O-GCDs will never return, Blood Price will never return, anything requiring you to take damage for more DPS will never return, it favours tanks over others completely.
