In Wow, the Hunter class is the most popular class in it. This is because the class is fast to level, easy to play. To get to know the Hunter, you should be familiar with its pet at first. Almost any class can use a bow or gun, and Warlocks get a certain set of demons to pick from, but Hunters are able to tame and work with practically any critter in the game. Cats, bears, boars, crabs, Bats, Owls and more, there's a pretty long list of critters to pick from.
   Besides the coolness factor, you can pick from bears, boars and cats when a critter has its advantage. Bears can soak the damage; boars can take some punishment and have a nifty charge ability and cats do not soak but they dish it out better.
   When you hit the Hunter trainer, you should make sure you hit the Pet Trainer as well. All the way you must keep your pet's health, growl and armor maxed out. As your pet levels up, it will get training points which you can spend on increasing its abilities.
In the same way, higher level critters have certain other abilities, so you will want to upgrade your pet occasionally. Take the stealthy cats as example; they are in Thousand Needles or Stranglethorn Vale. You are in position to miss your current pet and tame the new one. You'll also eventually gain any special abilities your new pet has and will be able to train other pets with those abilities.
The further your stats go, the more Agility you will want to get. It's your number one stat, figuring into your damage, Crit Bonus and your dodge. It even adds to your armor. Since you won't be engaging in melee combat (or shouldn't be, anyway) you'll have no use for Strength. Spirit is wasted on you.
Hunters do use Mana, but they don't use it as fast as a caster like Mage so while a little Int (to increase your mana pool) is nice, don't sacrifice Agility to get it. Stamina goes directly into Health, so more Stamina is always good, but you don't need as much as a front line fighter (Rogues, for example.) Look for Agility first, then Stamina, maybe some Intelligence, then skip the others.
Some gear comes with special abilities such as "Attack Power". This factors directly into your ranged damage so the more AP you can get the better. Other good ones to get are bonuses that add to your "Crit Rating" and/or Hit Rating.
At level10, when you get your pet, your usual attack pattern for the rest of your career will send the pet in, let it grab the target's attention and then start shooting the target. Hunters are very weak melee fighters, even with their special melee attacks. Mainly those attacks are to hamper the target, allowing you to get back into shooting range. To handle all the melee combat is your pet's job.
The goal of your attack will ignore your pet and charge you instead. Other players will always do this. If that's the situation then your freezing trap, wing clip, and concussive shots will allow you to get some breathing room. Feign Death works very well against monsters, but it won't work more than once against players.
At last, you should work on your Hot Keys. You'll want to bind your most used abilities to certain keys which you can easily reach while moving about. Try to develop a system where you can do the whole combat without ever having to use the mouse to click a target or activate a power.
All in all, the Hunter is a pretty versatile class. There is a lot of variety in pets and talents and many of the combinations one can come up with are quite worthwhile.
