Dont think in EQ

AGI lowers crit it and gives you more misses, but these things arent as important as lvls go up. Hence go with what they said, VIT. Try DEF but once you use Defender as a WAR and notice your not taking less dmg, your DEF cannot go higher, hence focus on VIT gear. There are soft caps for DEF and ATTK and EVA and stuff like that so once you deck em out, focus on that stats.
