Umm, Gigaflo? Check the numbers. Being dodged is as bad as missing; it reduces your DPS by exactly the same amount. Reducing your chance to be dodged by 1% is identical in effect to increasing your chance to hit by 1%. I know this is tough, but stay with me. Here are some formulas:
Expertise Rating conversion at lv70: 3.94:1
1 point of Expertise = 0.25% reduced parry/dodge
Expertise Raiting for 1% parry/dodge reduction: 15.77 (source: http://www.wowwiki.com/Formulas:Expertise
Hit rating for 1% improved hit chance: 15.77 (source: http://www.wowwiki.com/Hit
As you can see, the comparative values are identical. Now, your effective hit bonus required for specials is capped at 8.6% (3.6% with Precision), while your dual wield hit bonus is capped at 27.6% (22.6% with Precision). Therefore, any hit rating you gain above the amount needed to cap your specials is beneficial exactly in proportion to your ratio of white to yellow damage.
Critical hit rating also increases your DPS. How much? 23.6% gives you 1% increased chance to deal a critical strike. Without talents, this gives a flat 1% increase in your DPS (except for bleeds). Now, Rogues have several talents that improve the benefit of critical hits, such as Lethality (improved damage multiplier) and Seal Fate (extra combo points on critical hits). It's difficult to absolutely quantify these effects, but let's just say 1% crit = 1% DPS.
Let's assume a typical combat build, with 60% of your DPS coming from white damage and 40% from specials. Let's assume you have 5/5 Precision and are always attacking from behind (a decent assumption in raids). Now, by simple math
, the following calculations apply:
* Hit Rating, up to Special Cap: (64 rating)
1% rating = 1% DPS increase; 15.77 rating/1% DPS
* Hit Rating, up to Melee Cap: (65 to 363 rating)
1% rating = 0.6% DPS increase; 26.28 rating/1% DPS
* Expertise Rating, up to Cap: (88 rating, 49 with 2/2 Weapon Expertise)
1% rating = 1% DPS increase (from behind); 15.77 rating/1% DPS
* Critical Strike Rating: (practically, crit stops being effective around 40-50%, but this varies based on the encounter and your talent build)
1% rating = 1% DPS increase; 23.6 rating/1% DPS
You want Expertise Rating up to the cap (5.6%, 88 points, or 49 with 2/2 Weapon Expertise). Then you want Hit Rating up to your special cap (64 points). After that, Critical Strike Rating gives you more benefit, point for point.
You can speak emotionally or anecdotally all you want; the math doesn't lie.
