I think that you'd be able to sufficiently nerf Black Knight by changing their magic damage skills to physical damage. As Bright Bishop, Crescent Rook, and Boardshaker outperform any physical damage alternatives.

That is all I think would be necessary if we wanted to nerf them. However I feel that BK is only as good as it is right now due to the shifting meta where critical evade has become more valuable in light of luck no longer being a mandatory stat for evasion and crit.

I think BK could be touched, but I feel in the long list of priorities they are one of the few classes that lives up to their class mythos in a healthy way.
