I sincerely believe that we need to buff DK even more. The class is still far from reaching its full potential and the perfect balance we can achieve.
COF should restore 50% of maximum resources based on missing resources (including ultimate).
Corrosive should reduce all incoming damage to 3%, cost only 100 ultimate, allow DK to generate ultimate while active, and have its duration extended to 30 seconds.
Whip should deal Oblivion damage when fully stacked.
Wings should have their duration extended to 1 minute.
There is no way that the only reworked class should not shine in all aspects of the game — tanking, sustain, support, and damage. Yet Dragonknights are still not the top damage dealers in PvE.
We also have a strong lore-based reason to buff Dragonknights: they are practitioners of the ancient Akaviri arts, and history shows that the Akaviri were never successfully invaded. Their traditions form one of the foundations of the Cyrodiilic Empire.
