Run don't walk to STV to get yourself a pet gorilla. The few hours I spent playing with my new gorilla I thoroughly enjoyed. Their aoe special is spectacular, and along with our new much improved Volley we can aoe mobs down with ease.
After you find the gorilla of your choice (Petopia gorilla page), embark into the wild and aoe like mad (here is an aoe guide to help find locations). Remember, pet leveling has been buffed, so it is much easier to level a pet, and with aoe'ing you can level your pet even quicker.
So go out and enjoy your new aoe Hunter!
Update: It took me only 4 hours to level up my gorilla from 65 to 70! That's speedy fast compared to what it used to take... although part of the reason it was so quick was because of the aoe extravaganza!
