Title says it all; how should I deal with these classes in PvP? Most other classes seem to be pretty easy to beat provided I can get an opener on them... I just can't seem to beat these classes even in ideal circumstances.
Ferals I usually will open with a premed->recup->cheap->hemo->backstab->backstab->kidney->sd->ambush->ambush->recup->ambush, this gets them to half health, they go bear form and I slowly lose regardless of the various cds I use. I shiv whenever I see vengeance.
Blood DKs I open with premed->recup->garrote->hemo->backstab->kidney->sd->ambush->ambush->kidney->recup->ambush, I shiv vengeance and I pop my defensives but I can't seem to dent their health much, meanwhile they hit me like a truck and heal themselves. I cloak/vanish to garrote but it never seems to matter much.
My gear isn't all that great, but even lesser geared blood dks and ferals I have difficulty with.
