World of Warcraft Legion is bringing benefit to Gnomes by enabling them to play the Hunter class with a new kind of pet named Mechanical.
It is the responding change to the calls from players urging to have Gnome Hunter for long and the new pet is a surprise coping with the commercial talent of Gnomes in engineering. For Gnome and Goblin hunters they can tame the Mechanical from the beginning, while for other races they have to learn with the help of an Engineering crafted device.
This is the starting pet for Gnome Hunter with a name matching its appearance-- the Giant Mechanical Rabbit. While most Mechanical pets will be challenging to tame, requiring you to first locate them and then use your Hunter abilities in unusual ways.
Different from the previous pets that are eating like beasts, Mechanical will only be fed on Mechanical Bits created by Engineers. It seems like the spring of the Engineering crafts is coming.
