I hate to sound like an overly critical, nitpicky fanboy but that was Windcharger (or what was left of him) that Arcee laid next to Wheeljack. And I only bring it up because you actually succeeded in causing my brain to tweak in panic for 3/4 of a sec.

Mirage was/is one of my fave's and I actually had to resist the urge to swivel my chair and reach for the movie as my brain was simultaneously replaying that portion of the battle. It was a harsh scene for some of us older fans who saw it on the big screen. Just watching all of our favorites in general start to fall was tough. I remember having to bite my tongue when Brawn fell cause an expletive almost came out of me while I was in the midst of all these children and a handful of parents. (I was in my teens by then)
The cool part about todays technology is that, thanks to my friends digital projector, I got to play the movie for my own kids on a 54" x 76" section of wall. Not quite a theatre screen but still impressive with my surround system. So I got to watch their jaws drop like mine did during that battle sequence. The impact was the same as it was in '86. And yeah, I had to do a little damage control with my youngest son after the movie and assure him that Prime returns later. He was probably to young to let watch the film but I was prepared going into it.
