As an arms or fury DPS warrior, you need to strike a balance of many stats: Strength/AttackPower, Crit chance, Armor Penetration, Hit, Haste, and Expertise.

Wait..expertise?!?

Yes, Expertise, too. It was often overlooked for DPS warriors, because it was only found on tanking gear. However, we're seeing more items attractive to DPS classes with expertise rating on it, and so it makes sense that we should consider the amount of expertise on an item. But how important is it? Does it take the place of any of these other stats?

What You Need

As a DPS warrior, you should have the Weapon Mastery talent, that reduces your target's chance to dodge by 2%. Boss mobs have a 6.5% chance to dodge, and a base 9% chance for special attacks to be missed. If you are dual-wielding, white attacks have a 28% miss chance, but if you are using a 2-hander, white attacks only have a 9% miss chance.

Some more numbers before we continue:

3.94 expertise rating = 0.25% dodge reduction; 15.76 expertise rating = 1% dodge reduction.

15.76 hit rating = 1% miss reduction.

How do I value hit and expertise?

You've probably read elsewhere that your first goal as a DPS warrior is to get your hit rating to a magic number: 142 for arms warriors, and 95 for fury warriors. This is correct, getting there should be a priority, but not necessarily at the expense of your expertise rating.

Consider the following arms warrior trying to decide on his last trinket. Without it equipped, he has:

100 hit rating and 5 expertise (he's a human wielding a sword). He has no other expertise rating gear on, and he has the Weapon Mastery talent to reduce the bosses base dodge chance to 4.5%.

100 hit rating = 6.35% hit chance, and 5 expertise = 1.25% dodge reduction.

This means that his opponent still has a 2.65% chance to be missed, and a 3.25% chance to dodge: (9-6.35=2.65; 4.5-1.25=3.25).

In other words, each attack he makes, the boss will avoid it 7.9% of the time.

Now consider his two trinket options: Romulo's Poison Vial and Shard of Contempt.

If he equips the vial, he will gain 35 hit rating, increasing his hit rating to 135. The miss-reduction becomes 8.57% (still below the cap), and the bosses chance to be missed becomes 0.43%. The bosses dodge chance remains the same, 3.25%. Total chance to be missed: 3.68%

If he equips the shard, he gains 44 expertise rating, which translates to 11.16 expertise. Expertise rounds down, so this is 11 expertise. His new expertise is 16, which is a 4% chance-to-dodge reduction, and the bosses chance to dodge becomes 0.5%. The bosses chance to miss remains the same, 2.65%. Total chance to be missed: 3.15%

The warrior should choose the shard, even though his hit isn't capped, because the chance for the boss to dodge+miss is lower with the shard.

Conclusion

If you are not expertise-capped or hit-capped, but you have a Shard of Contempt, then EQUIP IT. There is no better trinket to increase your chance to hit the boss. It doesn't have hit rating, but it doesn't matter. If your hit rating is 142 but your expertise is 0, then you 4.5% of your attacks will still miss due to dodge. Because the reduction is equal (15.77 expertise = 15.77 hit = 1% reduction), 100 hit rating + 42 expertise = 142 hit rating + 0 expertise.

tl;dr: Focusing on hit and ignoring expertise is gimping your DPS. Don't gimp yourself by equipping bad hit-rating trinkets and bagging a good expertise-rating trinket. Yes, it's optimal to be expertise-capped AND hit-capped. But until you can get there, it's okay to drop your hit rating below 142 (or 95 if you're fury), if you are swapping in more expertise.
