Question about Tank stats

[Klamor]

To answer all your questions in one post:

1) Dexterity and Strength no longer have any effects on Parry Rate/Strength, or Block Rate/Strength that they had back in early 2.0 days. Parry is a flat 20% reduction, and the score simply increases the chance to parry by an albeit small amount per point.

2) Vitality and Strength are now both considered "main stat" for tanks, as they both give the same Attack Power contribution that previously was reserved to Strength with a 1:1 ratio. Now it's 1 Vit = 1 Str = 0.450 AP. For the most part, you'll want to be using Vitality accessories because those pieces have a higher stat capacity for Vitality than an equivalent item level Strength piece has for Str.

1 str = 0.45 attack power
1 vit = 1 str + 20 hp

True. The question on that topic was specifically regarding increasing DPS, however. HP is a no-though-required byproduct of equipping higher item level gear, regardless of how that actually affects your damage output via secondary stats.
