it depends what type of build you're doing, for tanking, yes vit, and str are your key components...if you're a dps, then dex and str is your friend, because dps stands for damage per second, and dex lets you dodge/avoid enemies attacks, and also lets you hit them more with auto attack, so it really depends on what ou're build is.
dodging doesnt increase dps, dex doesnt increase the attack that much with small amount, dex doesnt affect skills
in other words, for warrior, dex is almost crap, dont use dex, focus would be much better stat for dps (energy bonus), but dont use much focus too, vit and str is all u need ,i use 45 (270) str since i changed haste rings and 805 vit
but ofc str at 300 is what i had, i'll change it back when i'll be 170 and change from 75 str aggy brace to 60-60 str-vit brace
