Rather than allowing the chaos in PvP to continue whilst the class rework takes over two years, wouldn’t it be better for the DK to revert to its previous state?
I haven’t been playing the game for very long, but I don’t think the DK before the rework was any weaker than the currently underperforming classes—NB, Plar, Nec and Arc.
I think this might be a way to stabilize class balancing quickly.
I would recommend rolling out the update for all classes simultaneously after the all classes reworks are fully complete.
I believe that the balance up to that time can be maintained through fine-tuning of the pure Class mastery.
