At least in FFXI, accuracy was weighed against evasion. I dont think there's a visible evasion stat in this game and we can't check a mob's evasion to gauge our accuracy. In ffxi you can /check a mob and unless it was a boss or special type of mob(an NM is comparable to a hunt in ffxiv) it gave you a rough estimate of your hit rate. Accuracy does nothing 1-49 as you generally have enough acc to hit any mob within 5 levels of you...it goes pretty much ignored. Determination is also kinda weird but i guess it replaces the ffxiv 1.0 version of piety(which used to affect magic attack, and physical attack and is why drg has a high pIety compared to other non mages(they never readjusted drgs piety after changing what piety does...yay for drg mp).
