Hello people!
I whant to give some rough discription about the speccs so that we dont need to answer evry week what all the speccs are

Ok well their talents basically consists out of three speccs: Blood, Frost, unholy.
Blood: It is high dps against one mob, it is good for leveling, grinding but also dps'ing in groups and it gives you quite alot of life drain abilities.
Frost: Is more the tankish specc, I do not reccomend it for leveling because it does not have alot of life drain spells what blood and unholy do have.
But frost is the specc basically to tank with.
Unholy ( my favo) : This tree is very much concentrated on summoning ghouls and gargoyles, diseases, AoE and some drain life abilities.
And is quite outstanding in grinding and just good in leveling too.
I myself also recommend unholy level with because actually you fight alot as melee'r if you are worried that you will do more spells then really bashing head on. The unholy specc is a nice surviving specc what can kill a few guys head on without really loosing alot of health.
Blood I have not really tried out but I would say its more head on but I think it would take longer to level with because you cant pull as many then
unholy.
Hope this helps a bit if you want I can post my unholy specc I must say I looked a bit to James DK guide to for the unholy specc.
P.S. If any dks want to say something too or just wants to give their opinion please go ahead

Spud!
