For Hunters Agility is the only stat that can be used to increase their DPS, since Hunters are primarily ranged DPS. (Not counting raw AP, since this is the same for all classes; 1 AP = 1 AP ;) ).
Where warriors get 2 AP per 1 STR, Hunters only get 1 AP per 1 AGI, so Hunters require more of "their primary stat" (AGI) to get higher DPS, than a Warrior would require of "their primary stat" (STR).
The same goes for +Crit, where Warriors can get +1% Crit for only 33 AGI, Hunters require a full 40 AGI for +1% Crit, so Hunters often have to skip gear because they "only" have STA or INT, or low amounts of AGI.
A Warrior have a wider selection of weapnry to get AP from than a Hunter. A quick search found 5 weapons that have a lot more STR than this has AGI, between 51 and 75 STR, that's between 102 and 150 AP from the weapon, against only 100 the Warrior will get from this weapon.
As for the Crit Rating?
As Beast Mastery specialized Hunter, my pet is a significant part of my DPS. I have 3 skills that are directly dependent on me scoring a critical hit:
Kill Command - Allows me to let my pet instantly attack for a goodly amount of damage, which also can crit derived from my own Crit Rating, leading me to;
Ferocious Inspiration - Gives my party 3% damage increase, when pet scores a critical hit. Pet critical hit chance is directly dependent on my own.
Go for the Throat - Pet special abilities, that do a lot of damage, usually requires 50% focus to cast. This talent makes it possible for the pet to do this every time I score a critical hit, hence increase my DPS even more.
And just for the sake of completeness:
Expose Weakness - I know a lot of raiding Hunters are Survivalist specialized for this very Talent. The more AGI your Hunter have, the more benefit your entire raid will get.
Admittedly I know little about the talents/skills Warriors get, but from what little I do know, I haven't seen anything that makes a Warrior benefit from AGI as much as a Hunter will.
