Two hand weapons

I was wondering which stat is more valuable for a dk tank besides stam&armor,to be more specific two handed weapons have stam and str or agi.
Ik that str gives more attack power and increases your parry rating.. on the other side agi gives more crit and armor that gives bonus attack power from bladed armor which one shoud I consider more important?

Str weapons tend to have more stamina on them. Agi > armor > AP conversion from weapon is almost non-existent.
Secondary stats are also very important, so you want to have Expertise from Ramaladni or Glorenzelg. Slightly higher crit from Agi weapons won't be noticeable due to nature of your aggro generation.
