Ok, I haven't dual-spec'd Dusk yet. I did the priest and the warrior, but I have less than 4k gold left, and for some reason that makes me uncomfortable. And being dual-MM spec'd - not just that, dual PVE MM spec'd - well, ok, I already know I'm crazy.
So, my general spec hasn't changed too much - I bumped a couple points around to pick up Piercing Shots, and so I'm now 7/53/11. Major glyphs - Hawk, Serpent Sting, Trueshot Aura. Minor glyphs - Mend Pet, Revive Pet, Feign Death.
The second spec will be more optimized for raiding - so, cutting out things like Scatter Shot, and actually analyzing my haste rating and seeing just how many points I actually need in Improved Aspect of the Hawk... and then shoving all the extra points into things like Marked for Death (once I find out if it works with other hunters' marks) or Ranged Weapon Specialization (a talent I used to have, before they added so much fun stuff in 3.0).
I didn't actually test this spec much of at all. No, I logged out Monday night parked in Feralas, in order to begin farming Sprite Darters as soon as the server went up. Which I did, sometime around 8:45ish EST. I was all alone there until about 9:50, when another Tauren hunter showed up. The egg dropped for him after about five minutes. >.< Mine dropped at 10:00 on the dot, which was coincidentally the time I had decided I was going to stop a half hour before, so that I could go do the cooking and fishing dailies and buy the three new Horde faction mounts.
Small pets: 73; Mounts: 77.
Tonight: Gnomeregan! (For Lil' Smokey.) And then, assuming I'm not invited for Ulduar (I don't anticipate being asked to come), I'll start on the Emerald Whelpling.
