AF+1 pants are better than the Allagan ones since they have DET vs Crit and that DET stacks with the Allagan Battleaxe and the Allagan boots. Allagan Battleaxe is also ilvl95 so you're going to want that over +1. WAR suffers from accuracy problems as you're gearing up so you'll want the EX axe to not fall into that hole. Don't try to aim for BiS, just try to aim to hit the acc cap and if you happen to get BiS then good for you. The Allagan Chest and the Allagan accessories are great for WAR so try to get those in the meantime if they happen to drop.

Purchase wise, get either the ring or the chest first. You can also go for the gloves if you have the myth. From then on it's just about maintaining the acc cap for 1-4.
