Skullgrin doesn’t know that the autobots already know where the decepticon base is, galvatron is using it as an incentive to get to base before he gets himself killed.
I like how the deceptions aren't really the bad guys, and how you are showing how their is always two sides to every fight, but you ruined Optimus. You should have replaced Optimus' role with sentinels and put prime in hardheads role instead so later on prime would rise above sentinel.
