As it stands they give you
+65 Strength
+399 Haste
+340 Expertise
-254 Hit
-381 Crit
With my gear I'm already trying to get rid of expertise and my hit is really close to the cap. I can juggle around some stats to keep hit capped with the bracers, but That's a lot of crit to lose out on
If a piece of gear has 0 crit, it probably is not that good for warriors. Go for the Celestials 489 bracers, 1250 valor i think. Until then stick to the 5man bracers or get the conquest 483 bracers.
