I can see the point about Ironhide, but with NEST officially deactivated, there wasn't much for them to do at the base. It wouldn't have been that hard to come up with a scenario that frees most of the Autobots and gets them in on the action. That would have given them more screen time and would have made for a better movie. I hated how sidelined they were. Fangirl dream here, but it would have been awesome to Ironhide as acting leader in a fight scene.
