Eh.... dexterity counts towards dagger damage, hit rate and it allows a rogue to survive close-combat mobs. it is still the more important stat for melee rogues. I don't even pick up Lethality for Zevran until later in the game when I've gotten the other stuff he needs more. A bit of cunning + Lethality is just a boost to armor penetration and backstab damage.
This is a common misconception. It is not a matter of choosing between either dex or cunning for damage calculations. It is a matter of choosing between strength and cunning for both to hit and for damage, because with daggers AND with longbows, both the to-hit and the damage modifier is based on both the strength AND dex stats, unless you choose Lethality in which case it is based on Cunning and Dex. Either way you get the benefit of dex, but with higher cunning you get the added bonus of higher armor penetration, which improves actual damage numbers across the board, and higher backstab damage.
Here is the low down: dex can indeed modify to hit and dagger damage along with strength....or dex can do it teamed with cunning instead of strength, depending on whether you take Lethality and whether cunning is higher than strength. Assuming cunning is higher than strength (which is better be for a real rogue), and you take Lethality, then cunning becomes a combat modifier stat across the board, for ALL weapons, melee or ranged. If not, then all weapons default to their normal stat, be it strength, for swords and maces and such, or dex+str, for longbows and daggers. So you are left to choose which stat yields the greater overall benefits to your melee rogue, dex+str (w/o Lethality), or dex+cunning (w/Lethality). This one is rather a no-brainer. Then choose which stat, dex or cunning, should be higher to yield maximum benefits. And that choice is greatly simplified by the facts that cunning can add to your damage total TWICE, not just once, and that cunning also improves armor penetration to make more of your base damage actually count. Here is simple reduction of how it works, both for normal (face-to-face) attacks and backstabs:
DEX w/o Lethality:
1. Normal, you strike with your to hit chance modified by dex + strength, and then when a hit is scored you add your dex and strength modifiers to the damage. This damage number is then reduced by the target's armor score adjusted for your armor penetration (for which the only variable in this example is your cunning stat, which in this half of the example is assumed to be lower than dex.)
2. Backstab, as above except that you get a 50% bonus to damage (just like a crit), plus if you have Exploit Weakness you have added bonus damage based on your (lower than dex) cunning stat.
CUNNING w/Lethality:
1. Normal, you strike with your to hit chance modified by dex + cunning, and then when a hit is scored you add your dex and cunning modifiers to the damage. And then you reduce damage based on armor adjusted for your armor penetration (which in this half of the example is better because of your now higher cunning stat.)
2. Backstab, as above except that if you have Exploit Weakness you add your (higher than dex) cunning bonus in a second time.
So you see that with cunning as your primary stat, instead of dex, you get maximum use of the armor penetration and backstab components of damage calculation. And you STILL get to use your dex modifier to help with to hit and base damage calculations, except that you DON'T have to water it down with your presumably low strength stat, but rather can use your much higher cunning stat instead. With dex as your primary and no Lethality, you are stuck using your strength stat, which is likely quite lame, and your cunning stat plays no role. With Dex plus Lethality you are halfway in between, getting the advantage of using dex+cun for your base calculations, but still sacrificing in the areas of armor penetration and backstab damage due to your lower cunning score, thereby watering down the damage you can actually inflict.
When the calculations are all done, cunning is the hands down winner for both melee and archer rogues...and doubly so for the assassin specialization.
