I've currently been doing a little research, and I haven't been able to find any solid information pertaining which of these stats should take priority after accuracy.

My current gear setup is the following:

Weapon: Allagan Grimoire of Casting
Head: Summoner's Horn
Body: Summoner's Doublet
Hands: Summoner's Ringbands
Waist: Allagan Rope Belt of Casting
Legs: Summoner's Waistclout
Feet: Allagan Boots of Casting
Neck: Hero's Necklace of Casting
Ears: Tremor Earrings of Casting
Wrists: Hero's Braclet of Casting
Rings: Vortext Ring of Casting / Hero's Ring of Casting

I'm currently sitting at 458 accuracy without food buff, so I have a little wiggle room there.

Also:
Crit Rating = 531
Determination = 279

Any suggestions or information pertaining to this dilema would be very appreciated!
