What is the best way to bear DK, full quest items & some epics with a warrior? I take 5k damage with their attacks and i dont know how to win em :S

Disarm, spell reflect, run away.

dk sux vs casters :\

check his ablilitys, or talk with friend who's playing DK, do some duels, and analyse, what skill - and when is give him the advantage in a 1v1 situation, you will loose a lot of duels tho. but you will get better in predicting the DK's actions and what you have to do to deflect it, (spell reflect, disarm, fear and every other cd). i could write a book now, but i'm too tired ;p
wait for the patch, get better gear, practice and its fine ;)

@Knattiz depends on the DK's spec but yea i have to agree that good dk's wont leave you a chance if the duel is 1v1 ... tought warrior with a healer combo(druid/pala/priest) mostly is insane vs dk's and what ever part they have :)

to win a DK with less equip than u.. just go Protection Spec... jeje
it's the only way to have a chance

ye kinda hard beating a dk if ur not prot, and if u are just try reflect and stun him as much as possible

@Kayson

Coils are instant or have a cast? and what u can reflect? ( coil and..? )

u can reflect his diseases etc.

but if u reflect some shit attack, you must wait 10sec for reflect again ( if u still survive) and do it again :S

well reflecting his diseases is the best thing you can do really as well as trying to stun him on CD, you have to use all ur CD's I guess to bring him down so it's kinda unfair tho.

u can reflect his diseases
