Might get me flamed, but I think they’re balanced TBH. You don’t run into that many DK teams, and they all feel beatable. DKs are a tanky class with decent sustain damage. However, they don’t really have any burst and their damage is very predictable and easy to play around. Dks also don’t have much in the way of mobility, so they get punished hard by things like lock gateways or ports.
At this point, I see far more RMP/Wizard cleaves/WW monks than DKs. Lots and lots of WW monks.
However, this might change when Dazor’alor opens up. The new necrotic strike trinket might make TSG pants on head retarded. I guess we’ll have to see when we get there.
