Level 20 was busy for skills, and the rest of the 20s are no different. Rapid Killing, Go for the Throat, and Efficiency are probably good places for your talents in this level range.

Level 24 has a new rank of Raptor Strike, Beast Lore, and Track Hidden. Track Hidden is, ahem, basically useless. The increased stealth detection isn't nearly enough to make it useful in PVP (the rogue can still Sap you before he's in range of being seen), and the only PVE use I've ever found for it was the quest to find the Theramore spies in Dustwallow Marsh, because they blend in with the terrain too much even when you're close enough to see them, and they're neutral to you, so you have to hit them first. Beast Lore is a nice little utility spell that will give you a beast's stats, abilities when tamed, and diet in their tooltip when you mouse over them; it'll also tell you if they're tameable. So if you spot something cool and don't want to go to Petopia (because you'd have to tab out, etc.), you can pop this on the mob and see if it would be useful (oh, it's an
Level 26 will let you learn new ranks of Aimed Shot and Serpent Sting, and you'll gain Elemental Tracking. The more exciting new spell at 26 is Rapid Fire, which your points in Rapid Killing will reduce the cooldown on by a full two minutes. You won't get a lot of use out of this skill unless you're in a stand-and-shoot situation (since the point of haste is basically Steady and Auto Shots, and you don't get Steady till 50), but for boss fights (and even some elites), the extra damage will be noticeable. When you pick up Rapid Recuperation later, your shots will cost less while Rapid Fire is active.
When you get to level 28, it begins to look more like your higher levels are going to - four new skill ranks, this time for Aimed Shot, Arcane Shot, Aspect of the Hawk, and Mend Pet. You'll also learn Frost Trap, which is your area-of-effect (AoE) ice trap. Unlike Freezing Trap, it doesn't freeze targets in its area, but slows them down. This makes it useful for kiting, and it's a staple for getting at range from enemeies in PVP.
