hi there,

you did make a missconception at saying that the meelee dps with the two blades would be higher...which they wouldnt. Simply due to the dual wield hit penalty of 19%. Even as a full PvE-raid-hunter you wont have more than 9% tohit...it just makes no sense for hunters (no raid-hunter with 9% hit would wield either of these weapon choices...but hey!) which leaves you with 0% misses with the Quill and 15% misses with the blades. This affects white dmg only, but only fr white dmg the blades would come anywhere close to the Quill.
The real numbers in meelee dps would look far away from that calculation however, because of any hunter who knows what hes doing throwing in a single raptor while runnig past will be ~50% of all meelee. And Raptor is much better with the Quill.

What you say about dual +30 int entchants is perfectly right and these are great, especially as a Marksman with AotV active, but you can use ANY combination of one/main/off-handed weapons for that pupose and the difference between any lvl68-70 quest dagger and these is non-existant for a hunter, as the only difference will be the meelee dps which are just totaly out of interest.

With the upcoming 2.2 patch changes of AotV hunters wont have viper active all the time, but only when their mana-level is low (as any non-lazy hunter has done it until now already), which makes an int-dual-wield equip only suitable for switching...and therefore you wont need epic weapons as a hunter....really.

Besides that, manapotions solve any manatrouble a hunter might ever run into as long as he knows that spamming stings and arcane shot isnt anywhere close to dpsing...especially since hunter is the only class in the game that can use fel-manapots without any drawbacks...what makes a pure int equip even more obsolete.

The only and really only reason a hunter would choose these that i can see would be the looks...the only situations a hunter ever needs extra hp from weapons is in PvP...and two-handed weapons have always had the edge over dual-wielding for hunters in PvP for many reasons...its not only the raptor strike. if you can live without the extra hp, even the good old hakkari warblades are still quite eqivalent for a hunter...and look better.

A note to looks: Female Nightelves still suffer a glitch from the adjustment of the backmounted mainhand...the offhand will still be in the same place es before...which makes dual backmounted weapons look bad on female nightelves atm imho. And considering it took Blizzard 3 years to adjust the mainhand slot in the first place, i wouldnt bet on them making the offhand look right any time soon...

just my 2 cents.
