As others have said, Engineering's bread and butter is the glove tinker. 1920 strength/intellect/agility (which ever is highest) for 20 seconds on a 1 minute cooldown. Definitely more bursty when compared to the other non gathering professions. There are other "for fun" things you can do with engineering... It's really just personal tastes.
