Parry rates, block % and armor calculations

[ulti_19]

In tank role I want to know what really is the best stat to sink my 30 points in. Seems like roughly 1 vit is 10 hp around. Honestly I don't know if the 300 hp bonus would be better than having a higher parry rate and % of it plus some extra damage from strength to regain more hp from bloodbath for example. In some other games I play the armor and damage reduction more than make up for hp in the end. I'd rather have higher armor and take 60 less from each shot for example or more often than having a 300 plus hp pool from the stat choosing. Does anyone know the numbers and did the math, of exactly how much strength will increase the parry % by and how often parry occurs with dex? This would help me a lot when choosing and mixing armors for end game as I don't really want to test armors with different stats over and over if someone already checked it out. Thanks!
