Mained Dk since I started the game, cutting edge/glad xp and this is the least fun ive ever had playing Dk.
Unholy feels so damn slow and clunky in PvE, its also boring in PvP too though. I miss the unholy blight/blood boil playstyle (how unholy was in late WoD/HFC)
Frost same thing, it has an interesting tool kit in PvP but both PvE and PvP it is garbage and way too simple with nothing going on. BoS is a horrible designed talent that if it exists needs to be an “all in” talent. It needs to do massive damage otherwise delete it and put something that’s actually good.
I member when howling blast actually did good damage
