My favourites

Class - The hunter would be by far my favourite class. They are a ranged DPS class that have the ability to tame beasts. They have 3 specialization, Survival, Marksman, and Beastmaster. I just got mine to lv 90 and hope to replace my mage with him. He is the first toon I created when I started playing wow, he is specialised into the the beasmaster class, and has the most hours of game play logged.

Pets - Since the hunter is my most favoured and played class, my favourite hunter pet would be my celestrial bear. He is a rare spawn that takes days to camp to capture.

Land Mount - The mechanized chopper would be by far the best land mount there is. It has the ability to ride a second character with you in its side cart. It is an expensive mount that requires an engineer to create for you.

Flying Mount - The turbocharged flying machine would place as my #1 mount. Its is also and engineer created mount. Its a gyro copter that requires an engineer to ride.

Profession - Engineering is my favourite profession, since its required to use several of my favourite mounts, and has many awesome ability's such as explosives, parachutes, rocket boots and damage enhancing glove enchants.

Old School raid - Uldar tops my raid list for favourites. It was based in the Lichking expansion and in its time it was a long and difficult raid. What makes this one my favourite is the first boss encounter that is fought on mechanized mounts such as seige engines, demolishers and choppers.

Starting area - The goblin starting area in my opinion is the most unique area of them all. Its based in a sort of industrial area, with many quests unique to the goblin story line.
