Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey folks. I have just took lvl 30 and I cant decide which talent would be more useful in wPvP/BGs at this level. Should I go into assasination tree with Cold Blood or Preparation in subtlety?

Personally I would take hemo for PvP. The pve damage isn't that bad either.

In my opinion neither Cold Blood or Hemo/Prep are strong alone, but the combination of Hemo stunlocks and CB burst makes it a really good level 60 spec.

For PvP while levling I would go Riposte/ImpSprint/ImpKick-combat, since that build also is best for grinding.

If the Combat route does not tempt you, I suggest a Ambush/Backstab build, tho at low levles it lacks lethality critbonus:
