Has anyone noticed that Optimus seems to have little regard for his weapons and upgrades? For example, in ROTF, after he's done defeating The Fallen, he carelessly releases the extra parts he got from Jetfire and allows them to fall to the ground. Also, in DOTM, after his first encounter with Shockwave and the Driller, he throws his sword and his shield to the ground. Then, in the final segment of Dark of the Moon, he releases his flight-tech from his body and carelessly allows it to drop to the ground. Why is this? Why is he so careless with his weapons and his upgrades? Also, maybe if he hadn't tossed his shield after confronting Shockwave and the Driller, he would have stood more of a chance with Sentinel.
