Full STR WAR is nothing to write off.

[Marxam]

Unless you got extreme melded accessories and/or little to no i90 gear, 30 into vit is a must. With 2.1 however and the constant effect of defiance and wrath stacks no longer hindering the healing capability of a warrior I feel most of us wars will go the 30 str route.

My suggestion, only go 30 str if:

a) you can hit the next str threshold. I think it was 405 str but idr.
b) got more than 8k hp without food
c) all of the above

PS. I've crit for 954 (with my current gear) on butcher block in ak and I nearly shit my pants.
