DK is better for DPS overall though. When you can stay close to an enemy, then DK is much better for DPS.
There are bosses, where you have to keep some distance, but these are some expections.
DKs is my raid are the only class as a DPS who can stay near the Mage in Aetherial Archive. So if you know how to play, then even this is no problem.
Auri-El is my lord,
Trinimac is my shield,
Magnus is my mind.
