I've been doing PvP as a 2h Frost DK now for a while and just bought DW.
I now wonder what are the changes in my dps rotation? (Yea, I know it depends from situation, but is it just, dots up and spamm FS and OB when I can?)
From what I understand it's dispelling with IT, getting necrotic strikes up where needed, keeping obliterate on CD and using KM's on frost strikes, preferably with the blood tap talent. I'm not sure though.
if youre doing rbgs, just howling blast everything and you're set
