My understanding from reading the descriptions of the stats was that increasing STR increases the % damage parried/blocked, not the actual parry/block rate itself. Likewise, DEX seems to be the one to increase Parry/Block rates.0
STR - Affects physical melee damage, as well as damage prevented by parrying & blocking.
DEX - Affects physical ranged damage, as well as parry & block rates.
For my WAR tank I've gone 50/50 STR/VIT and end up with around ~5400 HP with Defiance on and around 31% damage reduction. I've wondered about taking a little away from VIT to just have around 5000 HP and putting some into DEX for increased Parry.
