IMHO the BiS link in the OP's post can be improved.

My config would be: http://xivdb.com/?wardrobe/4119/Dragoon-BiS

Everything is the same - just that opted for 2 Allagan Rings but the other opted for 1 Hero's Ring of Slaying.

End result is I sacrificed 11 Skill Speed for 11 Accuracy (Crit and Determination remains the same at 140 and 112 respectively).
