Seems pretty decent in PvP, no idea about PvE. Healing is nerfed to the ground but outside of that damage is pretty darn good and good Go’s feel rewarding both UH and Frost.
The one thing is you are definetly a bit squishy and susceptible to burst so you need to “kite” and “hide” a bit between cd’s. Rogues can burn you down quick if you aren’t paying attention but I feel that is a rogue issue more than a DK issue.
PS: I defo feel like Frost needs some buffs, probably not on the damage front but on the survivability front.
PSS: We are defo in a better state than S1 Shadowlands when we also had serious survivability issues, but UH was fairly trash and the only thing that made DK’s viable was Chill streak cleave that also got nerfed.
