Just wanted to continue this if only to confirm your findings with mine.
As fighters, our max Power is dependant on Strength. However, I am reading that AGI is more important later on, if you want to be a tank ( yes, contrary to popular belief, we can tank, esp. past lev 30). Having hp, with sta or more power with str is nice, the latter if true if you want to increase DPS, but having high Agility and not being hit is best.
