WildStar. It's a pet class, a ranged tank, a sniper, and a whole barrel of explosive mechanical fun all in one package.
Engineers have access to a stable of reliable bots to perform several functions, ranging from dealing damage to tanking to providing quick heals. The class also features a variety of ranged attacks, heavy armor, and a special exo-suit that allows them to bulk up and smash everything in range. Take a look at the latest edition of DevSpeak just past the cut to see the class in action, and check out the official site for a brand new installment of the Tales from Beyond the Fringe comic.
