I believe in my words and I say thoroughly that hunters can be easily leveled. Just go out for a coffee after sending your pet in near an auto fire. I am sure the result would be drastic!! You will notice that almost 3 mobs are killed by your pet because they might have attack you while you were AFK.

What is the best way to maximize your efficiency and reach the top level cap? I guess the answer is nothing else than the 'Beast Mastery Tree'.

I am sure by trusting The Beast Mastery talent, your pet will get efficient than ever before! Also it will become cozy for your pet to keep the enemy NPC's attacking him while you are busy making damages with the weapon!

Here you can see a nice leveling build for a Hunter:

Hunter Leveling Build

Choose Hawk Eye and Lethal Shots to boost your damage and range a bit.

From the Beast Mastery talent tree you can skip Imp Aspect of the Monkey because you will not be the one taking the hits. Imp Revive Pet isn't necessary for leveling. I would choose to put only one point into Imp Mend Pet because of the Dispelling purpose.

Thick Hide isn't bad at all but I would rather go with some damage abilities instead of some bonus armor.

When you prefer this build your pet will entertain:
+10% Health
+10% Crit
+100% Focus Regeneration
+9% Dodge
+10% Attack speed
+15% Damage
+10% Movement speed
+4 Additional Skill points

This all together with a lot of nice abilities that will be gained in this talent tree like Intimidation, which make the pet stun a target and creates a high amount of threat, Bestial Wrath, which causes the pet to do 50% (!) bonus damage for 18 seconds.

Through this talent tree like 20% Attack Speed, 5% Health, Improved Aspects and other nice boosts given from side to side by the pets abilities, the Hunter himself will also receive quite a few nice boosts.

Besides these abilities the Hunter and his pet will also move around the areas quicker because the Aspect of the Cheetah and Aspect of the Pack abilities will become more effective, a 10% mounted speed increase is given as well as a 10% bonus to their normal running speed.

Another nice thing of this talent tree is that the Hunter can Tame some creatures that otherwise could not be Tamed.

In total, the Beast Mastery talent tree is the way to set. . The Marksmanship talent tree looks great and it brings a new great boost to the hunter's smash! Anyway, you will observe that your pet cannot live the mobs on him and when it comes to your rescue- it doesn't look good! FOR PVP, the Survival talent tree is pleasant at anon levels!
