OFFENSIVELY gearing War... I would go STR > DET / SS > Crit .... Str and Det have direct gains, while SS has short tiers, and Crit has larger tiers. I would not be going offensive in Defiance, so I wouldn't count on that crit boost.

DEFENSIVELY gearing War... I would go, Str (until the next parry tier if reach able) > Parry (until the next parry tier) > VIT > DET. This is assuming you can reach those caps without sacrificing a LOT of other stats
